Future work should aim to characterize dream–wake continuity in specific ways, noting trends for specific memory features to be either largely continuous or discontinuous.3 This may help to alleviate concerns with discontinuity as being merely unexplained variance in models of continuity that aim to predict dreaming behavior. As we have noted, such discontinuity seems characteristic of both waking and sleeping cognition. Sleep (2001) 24(2):165–70. Hartmann E, Kunzendorf R, Rosen R, Grace N. Contextualizing images in dreams and daydreams. Traditionally, dreamlessness is defined at that part of sleep that occurs between bouts of dreams - a time of deep sleep when your conscious experience is temporarily switched off. This view is reiterated by Kozmová and Wolman (40), who point out that the differences between the findings of cognitive researchers and neurophysiological researchers may be explained by the fact that while Kahan and colleagues are focused on cognition within a dream, Hobson and colleagues in theories like the AIM model of dreaming focus more on features of dreaming such as uncertainty about people and places, and incongruous imagery. A novel demonstration of enhanced memory associated with emotional arousal. One stage of sleep, called rapid eye movement or REM sleep, is when dreams typically occur. We think that's to stop us acting out our dreams," she says. 71. doi:10.11588/ijodr.2011.1.9087, 15. doi:10.1192/apt.7.2.102, 79. By drawing upon evidence of the incorporation, fragmentation, and reorganization of memories within dreams, this paper proposes a model of discontinuity whereby the fragmentation of autobiographical and episodic memories during sleep, as part of the consolidation process, render salient aspects of those memories subsequently available for retrieval in isolation from their contextual features. Schredl M, Hoffman F. Continuity between waking activities and dream activities. 5. Behav Brain Sci (2000) 23:793–842–1121. 76. Other examples combining high-level metacognitive functioning with a loss of engagement with reality include experience deja-vu, having involuntary autobiographical memories (AMs) interrupt focused thought, and meditation. 55. Indeed, a dream that is continuous with waking life should, in theory, feature real experiences, or AMs. 31. Cartwright RD. Rather, discontinuity in sleep, and likely in wake also though perhaps to a lesser extent, may reflect offline processing that maintains the organization and consolidation of experiences within a neurocognitive system that is constantly being updated. doi:10.1037/1053-0797.16.3.196. We argue that this assumption is oversimplified. ... Start studying How does sleep affect consciousness. No, You Were Not Happier Way Back When. However, intoxication, often with alcohol or marijuana but progressively more commonly through prescription medications, can produce the same effect. Or the conscious act of daydreaming: a part-focused activity perhaps with a pleasant goal but one that requires fantasy, mind-wandering and a loss of engagement with reality. Indeed, these emotional experiences may be particularly pertinent. Furthermore and not unrelatedly, some individuals are more vulnerable to experiencing dissociation than others. Every day, from minute to minute and hour to hour, our consciousness moves through different levels of wakefulness and productivity. Dreaming is the most prominent example, but there is more to conscious experience in sleep than dreaming. Harvey AG, Jones C, Schmidt DA. Annu Rev Psychol (2002) 53:1–25. If we proceed with our definition of consciousness as a holistic experience of the present, brief past, long-term past (via memory retrieval) and the future (goal directed), we may assume that the ability to recall prior experiences, i.e., for continuity to function, would allow focus to be maintained in reaching future goals. Horton CL, Smith MD, Proctor C. The emotionality of dream memory sources: intensity and valence influences likelihood of incorporation. This may appear counterintuitive but suggests that discontinuity is a functional end-point of a cognitive process of integration and consolidation. However, we must be careful not to over-simplify these findings, recognizing that volition is still possible during sleep, as evidenced by the wealth of empirical work into the experience of lucid dreaming. doi:10.1016/j.smrv.2014.03.005, 72. One is coma — unresponsiveness to outside stimuli, plus a brain that can't accomplish much beyond the amazingly complicated process of keeping you alive. Autobiographical memory and hyperassociativity in the dreaming brain: implications for memory consolidation in sleep. Imagination Cogn Pers (2002) 22(3):257–76. (7, 18)]. Just as we move in and out of alertness, ranging from paralyzed semi-conscious television watching to our lives' creative peaks, what we remember and what we don't involves many different shifts of consciousness. While this may seem unsurprising as the act of reporting a dream could be seen to rehearse those original experiences, the representation of the experience in the dream was often far different to the original episode. Nevertheless the relationship between REM sleep and novel ideas has been shown in a number of empirical investigations exploring not only creativity but also problem solving and insight. The sleeping therapist: do we dream to process emotional waking experiences? Payne JD, Ellenbogen JM, Walker MP, Stickgold R. The role of sleep in memory consolidation. doi:10.11588/ijodr.2011.2.9147. It's more like putting nine separate orchestras in different sections of the Houston Astrodome, some in the boxes, others on the field, a few players in the washrooms, and getting them to simultaneously play the same notes in the same rhythm. Hobson JA, Pace-Schott EF, Stickgold R. Dreaming and the brain: toward a cognitive neuroscience of conscious states. Stage 1 sleep demonstrates that states of consciousness not only fluidly run into each other, but often are not recognized. Marshall L, Born J. Somewhat relatedly, models, such as Schredl’s (1, 62), attempt to characterize the likelihood of recalling dreams and even dreaming of specific material. No one knows! Landmann N, Kuhn M, Piosczyk H, Feige B, Baglioni C, Spiegelhalder K, et al. REM, not incubation, improves creativity by priming associative networks. You often see it in elderly people, who will shift suddenly from talking about the stock market to forgetting your name or where they are. Walker MP, van der Helm E. Overnight therapy? We also alter our consciousness through the use of various psychoactive drugs. Dreams are interesting because you actually feel like you are conscious, but you're not conscious in the same way you are when you're awake. 3. It turns out that anesthesia is a lot closer to coma than some people thought. Continuity between dreaming and waking, therefore, appears to provide a framework for studying and measuring the extent of overlap, or shared variance, between different states of consciousness (11). Neural correlates of insight in dreaming and psychosis. Fosse MJ, Fosse R, Hobson JA, Stickgold RJ. The continuity and discontinuity of dreaming mentation has to date been explored in a handful of studies, with the latter in part being related to the experience of bizarreness. J Exp Psychol Gen (1984) 113(3):329–44. Deep sleep. State-dependent thinking: a comparison of waking and dreaming thought. The role of sleep in changing our minds: a psychologist’s discussion of papers on memory reactivation and consolidation in sleep. A person with sleep apnea stops breathing while they sleep due to obstruction to their airway. If not how do we know the sleep experience. This gives rise to the possibility that the dreamer can process, or think about, scenarios that would not be encountered in waking life, perhaps as a rehearsal strategy of some kind [e.g., Ref. Sleep is the normal rhythm of life. This final section will consider hypnotic and meditative states as additional examples of altered states of consciousness … Trends Cogn Sci (2001) 5(9):394–400. doi:10.1038/nrn2716, 24. While we all experience altered states of consciousness in the form of sleep on a regular basis, some people use drugs and other substances that result in altered states of consciousness as well. Consciousness is not just a bunch of different levels. doi:10.1093/sleep/23.6.1, 59. 11 In cognitive psychology, this would represent a weak semantic association rather than a strong one, with the latter typically reflecting focused thought and goal-oriented processing. They just thought they were awake — and argued vigorously with the researchers, even when shown videotapes of what they did during those 10 minutes. While sleep patterns change as we age, the ... At our deepest level of sleep our brain waves actually resemble our _____ Do we sleep more if we are physically active? The activation of prior experience in a truly continuous manner would mean that we need to access all aspects of that prior experience. The editor and reviewers' affiliations are the latest provided on their Loop research profiles and may not reflect their situation at the time of review. Does anesthesia put you to sleep? Themes of continuity. Does Your Brain Wake Up When You're Dreaming? An interesting caveat to the generalization about dreams versus daydreams comes from Kunzendorf et al. This presents a challenge with conceptualizing continuity and discontinuity in operational terms. doi:10.1162/089892903321107774. Kahn and Hobson (36) further account for the lack of reality monitoring during REM sleep dreaming by the reduced activity of the dorsolateral prefrontal cortex and precuneus, as well as the functional disconnect between these structures (32–34), meaning the brain cannot distinguish between who, where and what we are within a given context. We have so many opportunities to change our state of consciousness and create a new world. To this end, discontinuity seems to allow novel insights and creative possibilities. However, very few individuals wake from a dream experiencing a sudden moment of clarity or enhanced understanding into a problem. Conway MA. When we are asleep than when we are awake. Posted on August 28, 2018 (August 28, 2018) by admin. Hartmann, however, did not speculate as to what the function of such hyperassociativity may have been, although he was a psychoanalyst and so believed that dreams had a language that could be uncovered therapeutically. Horton CL, Conway MA, Cohen G. Memory for thoughts and dreams. A recent study (83), documented the incorporation of recent autobiographical experiences into dreams that had been documented in a 14-day diary. 5. This final section will consider hypnotic and meditative states as additional examples of altered states of consciousness … However, unexplained variance remains so high (91.6%) that these models have many more factors yet to uncover in the pursuit of understanding the nature of dreaming. At first glance, this may appear to be at odds with literature and evidence demonstrating that dreaming cognition, as a reflection of rapid eye movement (REM) sleep (13, 17), is dissociative and, therefore, symptomatic of psychosis. This is essentially a state somewhere between stage 1 sleep and wakefulness, and can lapse in and out of the two for many minutes before people stop hitting the snooze button and actually rouse themselves out of bed. (10, 77)]. Furthermore, most theories of consciousness distinguish between the more essential and automatic processes of responding to environmental needs, and the high-order cognitive processes of awareness of self in place and time [e.g., Ref. The content of this field is kept private and will not be shown publicly. doi:10.1016/S0272-7358(03)00032-1, 51. Cartwright (76) also reports of her studies with divorcees, who dreamed of their divorce process over time, and the shift from dream reports being more accurately reflective of current concerns and experiences, to being more symbolically represented as the divorce process was appraised and comes to terms with by the dreamer. Our states of consciousness change as we move from wakefulness to sleep. doi:10.1093/brain/120.7.1173, 33. Sleep Med Rev (2015) 20:92–9. It all comes down to FOCUS – what we think about and where do we direct our attention eventually becomes our reality. doi:10.11588/ijodr.2011.2.9149, 7. Schreuder BJN, Igreja V, van Dijk D, Kleijn W. Intrusive re-experiencing of chronic strife or war. To get to stage 1 sleep you need dozens of different kludges to work seamlessly together. Kahn D, Hobson JA. We also alter our consciousness through the use of various psychoactive drugs. This provides a starting framework for exploring links between (dis)continuity and memory consolidation of declarative experiences. Hamann SB. Also, if continuity involves recalling past experiences holistically, discontinuity could refer to recalling them in a fragmentary manner. A new approach to dream bizarreness: graphing continuity and discontinuity of visual attention in narrative reports. If continuity refers to the ability to retrieve the past, and the future where relevant (goals), in the context of present awareness (consciousness), then it would follow logically that discontinuity is the opposite of this, whereby discontinuity would be the inability to retrieve the past or future in the context of the present. (57), see also (58)]. Our brain profoundly alters its behavior and purpose, dimming our consciousness. Dissociation can be exacerbated by sleep loss (45) and sleep disturbances are symptomatic (or perhaps even causal) of virtually all mental disorders as listed in the DSM-5 (43). J Sleep Res (2000) 9:207–31. What Might be the Function of Continuity? Such studies of discontinuity could inform much about the activation of autobiographical experiences across different states of consciousness. American Psychiatric Association. However, discontinuities have been somewhat dismissed as being either a product of activation-synthesis, an error within the consciousness binding process during sleep, a methodological anomaly, or simply as yet unexplained. Previous studies have explored the overlap, or continuity, of cognitive processing style from waking life to dreaming. The behavioral outcome, i.e., what is consolidated and/or consciously experienced is, more often than not, unclear upon awakening and usually later following dreaming. More bizarrely, sleeping pills like ambien (zolpidem) seem to produce states that ape parts of coma. Sleep (1983) 6(3):265–80. Front Psychol (2015) 23(6):1957. doi:10.3389/fpsyg.2015.01957, 86. Rather than experiencing just different levels of consciousness, we normally undergo many different states. As the dream memory fades so quickly and it is only in the case of the few avid dreamers who may engage in consideration of their dream experiences that they claim to have an understanding of what their dream “meant” or represented, we cannot assume that a clear purpose of dreaming is to have conscious clarity or insight following the dream experience. (63)]. 1. doi:10.1073/pnas.012689199, 69. Behav Brain Sci (2013) 36:589–607. Memory processes during sleep: beyond the standard consolidation theory. Thus, consciousness in part involves the activation and awareness of memory. 70. It is also interesting to note that daydreams generated under the influence of extreme emotional intensity are more “dream-like” and more symbolic than any other kind of daydream (61). Sleep Hypn (2005) 5(1):26–40. (22, 23)]. Consciousness can be temporarily abolished … This awareness of the origin of events as being either internal, such as a thought or a dream, or external in that it is truly perceived, is known as reality monitoring (37). The individual may or may not be aware of these awakenings which can occur hundreds of times each night. Trends Cogn Sci (2007) 11(10):442–50. Furthermore, some studies have implied that there exists a relationship between continuity and emotional intensity, such that the more intensely emotional the experience, the more highly continuous it is, especially if it is traumatic in nature [e.g. Development of disturbing dreams during adolescence and their relation to anxiety symptoms. Furthermore, sleep appears to afford opportunities for the reorganization of memory networks (22, 65, 71, 72) and thus the integration of newer experiences into pre-existing cortical structures (70, 73–75). Exploring the role of need for cognition, field independence and locus of control on the incidence of lucid dreams during a 12 week induction study. doi:10.1093/cercor/bhn155. Memory of sequential experience in the hippocampus during slow wave sleep. REM sleep. It's kind of like thinking of a plywood two-by-four as potentially part of a table, the base of a floor, a weapon, bed headboard, elevator, plane for writing, carved signboard, room divider, toy, plus who knows what else. An alternative body of work from both the sleep and dreaming fields explore the creativity associated with REM sleep (in particular). 5th ed. The breakdown of holistic conscious experience is also reflected in dissociation; detachment from either the perception of reality or separation of the experience of the past. In addition, as with the function of any memory system, the ability to recall prior experiences is the consequence of successful learning and allows those experiences to shape our interaction with the world in light of them. Some short-term approaches have looked at the organization of memory representations across the night, with early-night sleep being rich in non-REM, slow-wave sleep, and later night sleep being richer in REM (7). doi:10.1046/j.1365-2869.7.s1.7.x, 35. We don’t have to become unconscious when we sleep. doi:10.1073/pnas.0900271106, 64. van Heugten-van der Kloet D, Cosgrave J, Merckelbach H, Haines R, Golodetz S, Lynn SJ.

Dreaming and cognition in patients with frontotemporal dysfunction. This paper summarizes the elements of continuous and discontinuous processing across sleep and wake, recognizing that discontinuities in form, of cognition and of consciousness are typical and indeed functional of waking processing as well as in dreams (i.e., sleeping processing). Dreaming and episodic memory: a functional dissociation? A handful of dream studies have been able to map the activation of a specific memory source over time, although unfortunately these studies are varied in their methodological approach. Salient fragmented memory features are activated in sleep and rebound with fragments not necessarily emerging from the same memory, thus de-contextualizing those memories and manifesting as experiences that differ from waking conceptions. The constructive nature of autobiographical recall further encourages synthesis of these hyperassociated images into an episode via recalling and reporting dreams. doi:10.1016/j.tics.2007.09.001. Hopefully in the future sleep study technology will afford the more accurate monitoring of this with neural mapping of the activation of the original memory engram along with a representation of the extent to which it has been integrated into long-term cortical structures. It also seems somewhat optimistic to characterize waking thought as consistently focused and efficient. 62. Stickgold R, Fosse R, Walker MP. For instance, some existing work has identified benefits of a labile sleep–wake pattern in terms of the number of cycles through sleep stages upon knowledge awareness tasks (84, 85) and recent work has identified that lucid dreaming training benefits performance in field independence tasks (86). Front Psychol (2015) 6:324. doi:10.3389/fpsyg.2015.00324, 65. 1. Discontinuity could present as disjointed cognition, with absences or lapses in attention (i.e., consciousness being interrupted). As such, consciousness is extremely discontinuous, particularly with its focus sometimes being on the external environment and sometimes detaching from this almost completely, with the conscious awareness being directed toward internal states of reflection. doi:10.1016/j.concog.2011.03.022, 17. The consequence here is that experiences that have been well integrated into a memory network and that have been processed emotionally, would not manifest in dreams in a manner that largely reflects their original experience in waking life. Domhoff GW, Meyer-Gomes K, Schredl M. Dreams as the expression of conceptions and concerns: a comparison of German and American College Students. Dream recall and confabulation. Llewellyn postulated that this process in dreaming operates to create episodic “landmark junctions” at a neural level. Dream researchers, on the other hand, use a variety of methods to capture fragments of conscious experience from sleep, including at times relying on spontaneous awakenings or the “most recent dream” method of recall and report, which likely bias findings to a sample of REM sleep dreams. However, some will be salient enough to require consolidation into long-term memory networks, to be accessible for future use and to require prior knowledge to be updated. Imagination Cogn Pers (2006) 25:269–82. Dreaming (2006) 16(3):196–214. Spiegel D, Lewis-Fernandez R, Lanius R, Vermetten E, Simeon D, Friedman M. Dissociative disorders in DSM-5. doi:10.1037/1053-0797.15.3.155, 49. Similarly, during sleep prior experiences may be activated either in full [rarely; see Ref. While we all experience altered states of consciousness in the form of sleep on a regular basis, some people use drugs and other substances that result in altered states of consciousness as well. Cai DJ, Mednick SA, Harrison EM, Kanady JC, Mednick SC. Conway MA, Loveday C. Remembering, imagining, false memories & personal meanings. Foulkes D, Schmidt M. Temporal sequences and unit composition in dream reports from different stages of sleep. Emotion makes daydreams more dreamlike, more symbolic. Nishida M, Pearsall J, Buckner RL, Walker MP. That may refer to dreaming of an event from waking life in a very different way to the original experience, or it may refer to simply recalling an experience in a different way to its original occurrence. 2nd ed. Front Psychol (2013) 4:474. doi:10.3389/fpsyg.2013.00474, 73. REM dreams are typically bizarre (48, 49), featuring sudden changes and eliciting feelings of strangeness, curiosity or mystique upon awakening. Conscious Cogn (1998) 7(7):634–46. put people into stage 1 sleep for 10 minutes. Front Neurosci (2009) 3(3):418–9. Often they are not experienced as microsleeps, or even as blips of changed consciousness — with sometimes fatal results. Barrett D. Trauma and Dreams. References. Generally they are not remembered — because you're in deep sleep. Llewellyn S. Such stuff as dreams are made on? When Is the Best Time to Meditate for Better Sleep? Once psychology was established as a discipline separate from philosophy and biology, the study of the conscious experience became one of the first topics studied by early psych… The hyperassociative processing style, or “loose” connections in Hartmann (21) terms, provide a mental space for creativity and novel solutions to become conscious. Consciousness may be defined as our awareness of our environment, our bodies and ourselves.Awareness of ourselves implies meta-awareness or … Here, the authors compared cognitive functioning in dreams with that of wake, by asking participants questions about specific dream experiences. Baylor GW, Cavallero C. Memory sources associated with REM and NREM dream reports throughout the night: a new look at the data. When we are anesthetized before an operation or experience a concussion after a knock on the head, we may lose consciousness entirely as a result of changes in brain activity. In their study, Kozmová and Wolman (40) identified thought units as featuring cognitive or metacognitive processing, such as being analytical or operational, and in doing so illustrated the complexity of cognitions available in dreaming, concluding that the content of the dream (be it bizarre or not) does not preclude the application of rational thought, much like one would in waking life, and in fact the thought processes applied to a dream situation have much in common with those applied to a situation experienced in waking life. The risks and benefits of losing consciousness while asleep By definition, to be asleep is to be unconscious. Int J Dream Res (2016) 9(Suppl 1):S56. Memory sources of dreams: the incorporation of autobiographical rather than episodic experiences. Cereb Cortex (2009) 19:1158–66. Malinowski JE, Horton CL. Such a view is largely at odds with more contemporary approaches to dream science, in which memory sources of dreams are deemed to reflect more explicitly the activation of waking-life experiences that may be processed during sleep, perhaps as part of a memory consolidation process (2–4). Psychol Bull (2009) 135(5):731–48. Rather just that dream scientists have much work to do! Furthermore, this seems characteristic of sleeping mentation as well as wake (8, 29). Tulving E. Precis of elements of episodic. Temperature controls disappear, while the many kludges of the brain seem to communicate with each other in a sometimes forlorn attempt to take the new information of the previous day, anneal it with old memories, and remake it into newer information the body then uses to remake itself. When it was over, fully half thought they were awake the whole time. Dreams have been described as dress rehearsals for real life, opportunities to gratify wishes, and a form of nocturnal therapy. doi:10.1037/a0016570, 81. Malinowski JE, Horton CL.

One way of conceptualizing continuity then is in terms of the activation of memories across time. Strauch I. REM dreaming in the transition from late childhood to adolescence: a longitudinal study. By drawing upon evidence of the incorporation, fragmentation, and reorganization of memories within dreams, this paper proposes a model of the fragmentation of autobiographical and episodic memories during sleep, which manifest as discontinuity during sleep, rendering salient aspects of those memories subsequently available for consolidation in isolation from their contextual features. doi:10.1016/j.smrv.2014.06.004, 16. Trends Cogn Sci (2010) 14:88–100. Imagination Cogn Pers (2014) 34(2):163–77. Front. It also assumes that any as yet explained variance may be problematic, or simply, “error.” Indeed, discontinuities have been somewhat dismissed as being either a product of activation-synthesis [for instance, see Ref. However, under the backdrop of continuous consciousness, whereby the stream of thoughts, images, and cognitions are sewn together into a coherent narrative, individual memory fragments are bound together to create a new “episode,” which is certainly discontinuous from waking life as it may be implausible, incongruous or impossible (e.g., dreaming of talking to someone who has recently passed away). Memory for those original experiences was tested via recall and recognition. (59) reported that dreams were more bizarre, more “dream-like,” and more emotional than daydreams. Cognitive and neural mechanisms of emotional memory. Psychol Sci (2008) 19(8):781–8. The continuity hypothesis (1) posits that there is continuity, of some form, between waking and dreaming. As such while sleep may help to maintain order of consciousness and overall mental health, it apparently does not reflect continuity of it.2. Delirium. As distinct stages of sleep are defined by specific patterns of neural activity, measured using electroencephalogy, we assume that cognition during sleep changes also. doi:10.1046/j.1365-2869.2003.00344.x, 13. As Hartmann (21) suggested, but did not test empirically, REM sleep cognition may be hyperassociative, in that the links from one activated thought to another are more tenuous than in waking. States of consciousness vary over the course of the day and throughout our lives, and sleep plays a major role in alertness levels. doi:10.1037/0096-3445.113.3.329. Neuron (2002) 36:1183–94. Why Romance Movies May Be a Social Problem, 6 Simple Steps to a Happy, Thriving Relationship, How a Celebrity Crush Can Impact Your (Real) Relationship. During wake the human brain perceives a great wealth of novel information that requires processing and integration with existing structures. Stickgold and Walker (42) presented a “triage” model of sleep-dependent memory consolidation, whereby salient aspects of an experience are tagged as requiring processing during sleep. Cicogna PC, Bosinelli M. Consciousness during dreams. This paper attempts to clarity this and proposes a workable conception of continuity, with reference to the retrieval of prior experiences into consciousness at any given time. Malinowski J, Horton CL. doi:10.1017/S0140525X00004015, 40. 20. In sum the discontinuities of cognition in dreams have been recognized as being both typical of normal sleep mentation behavior, and possibly indicative of problematic dissociative symptoms, such as schizophrenia [e.g., Ref. doi:10.1007/7854, 68. They were not. Furthermore, scholars should continue attempting to identify whether patterns of discontinuity and continuity are consistent or varied across individuals. We lose consciousness when we fall asleep, at least until we start to dream. Llewellyn S. If waking and dreaming became dedifferentiated, would schizophrenia result? For example, individuals with direct military experience of war have direct, unambiguous, and sometimes apparently veridical dream incorporations of their experiences; civilians, on the other hand, have “indirect” or “symbolic” incorporations (78).
