From December 2024 to October 2025, the Israel Museum in Jerusalem presented Lucid Dreams, an interdisciplinary exhibition marking the centenary of Surrealism and of André Breton’s Manifesto of Surrealism (1924). Curated by Adina Kamien, the exhibition brought together some 180 works and objects, including Surrealist and contemporary art, dream- and sleep-related multicultural, religious and...
Magneto/electroencephalography (M/EEG) studies of dreaming are an essential paradigm in the investigation of neurocognitive processes of human consciousness during sleep, but they are limited by the number of observations that can be collected per study. Dream research also involves substantial methodological and conceptual variability, which poses problems for the integration of results. To...

Mesial frontal and temporoparietal brain areas differ in activity between high and low dream recallers, and lesion studies have found cessation of dreaming in patients with damage to these areas. This study extends these findings by assessing the relationship of dream cessation, and dream and nightmare frequencies, to severity of injury in patients at a head trauma clinic. 52 participants (M =...

The chapter begins with the text of a dream which includes themes of lucidity and control of the dream, told to us at an event at the University of California Los Angeles, and a painting of the dream and a commentary on its composition. Main content: The chapter describes how lucid dreams are a rare form of dream because the metacognition in them seems to be fragile and short-lived, and because...
The chapter begins with the text of a dream told to us as part of an online event for the International Society for the Study of Surrealism, a painting of the dream and a commentary on its composition. Main content: This chapter gives examples of the use of dreams in linear narrative films, sometimes as plot devices, and then compares this with films that are oneiric, that is, films that have...
The chapter begins with the text of a dream from a neuroscientist who studies what happens in the brain when dreams are produced, told to us as part of a sleep conference, and the painting of the dream and a commentary on its composition. Main content: This chapter addresses why people differ in how often they remember or recall their dreams. It concludes that the main reason for differences...
The chapter begins with the text of a dream with three related but very separate scenes, and a painting of the dream and a commentary on its composition. Main content: This chapter describes how dreams occur in all stages of sleep, but are recalled more often from REM than from NREM sleep. Furthermore, REM dream reports (measured by the number of words) on average are longer than NREM dream...
There are many theories of the function of dreams, such as memory consolidation, emotion processing, threat simulation and social simulation. In general, such theories hold that the function of dreams occurs within sleep; occurs for unrecalled dreams as well as for dream that are recalled on awakening; and that conscious recall of dreams is not necessary for their function to occur. In...
While material from waking life is often represented in dreams, it is less clear whether and how dreams impact waking life in return. Here, we assessed whether dream mood and content from home diaries predict subsequent waking mood using both subjective self-report and an objective automated word detection approach. Subjective ratings of dream and morning mood were highly correlated within...
Propensity to have nightmares has been theorised in terms of diathesis-stress models, with this propensity being seen as negative or even pathological. In contrast, a recent model proposes that nightmare propensity is due to Differential Susceptibility to stimuli, where high susceptibility can be beneficial in positive environments but detrimental in negative environments. This susceptibility...
Previous experiments combining cognitive techniques and sleep disruption have been relatively successful in inducing at-home lucid dreams over training periods of 1-week or more.Here, we induce lucid dreams in a single laboratory nap session by pairing cognitive training with external stimulation.Participants came to the laboratory at 7:30 am or 11:00 am and during polysomnography setup were...
Abstract Although gender differences in the dreams of adults have been studied extensively, large-scale studies in children and adolescents are scarce. The UK Library Study collected 1,995 most recent dreams of children and adolescents. Boys reported more physical aggression and fewer female characters in their dreams, whereas indoor settings were more prominent in girls’ dreams, results that...
In general, dreams are a novel but realistic simulation of waking social life, with a mixture of characters, motivations, scenarios, and positive and negative emotions. We propose that the sharing of dreams has an empathic effect on the dreamer and on significant others who hear and engage with the telling of the dream. Study 1 tests three correlations that are predicted by the theory of dream...
Throughout history there have been reports and claims that consideration of dreams can produce personal realizations and insight. We assessed Exploration-Insight scores associated with discussing Rapid Eye Movement (REM) and non-REM (NREM) dreams in connection with recent waking life experiences. Thirty-one participants were cued in the sleep laboratory for a daydream report and then awakened...
Rapid eye movement (REM) sleep and its main oscillatory feature, frontal theta, have been related to the processing of recent emotional memories. As memories constitute much of the source material for our dreams, we explored the link between REM frontal theta and the memory sources of dreaming, so as to elucidate the brain activities behind the formation of dream content. Twenty participants...
Incorporation of details from waking life events into rapid eye movement (REM) sleep dreams has been found to be highest on the 2 nights after, and then 5-7 nights after, the event. These are termed, respectively, the day-residue and dream-lag effects. This study is the first to categorize types of waking life experiences and compare their incorporation into dreams across multiple successive...
This study investigates the time course of incorporation of waking life experiences into daydreams. Thirty-one participants kept a diary for 10 days, reporting major daily activities (MDAs), personally significant events (PSEs) and major concerns (MCs). They were then cued for daydream, Rapid Eye Movement (REM) and N2 dream reports in the sleep laboratory. There was a higher incorporation into...
Several studies have demonstrated that dream content is related to the waking life of the dreamer. However, the characteristics of the memory sources incorporated into dreams are still unclear. We designed a new protocol to investigate remote memories and memories of trivial experiences, both relatively unexplored in dream content until now. Upon awakening, for 7 days, participants identified...
Although dreams are very private experiences, they are often shared with others. The findings of the present study ( N = 1,375) indicate that sharing dreams is indeed very common and that dream sharing frequency is related to gender (only in adolescents, with girls sharing dreams more often than boys), extraversion, dream recall frequency, and nightmare frequency. Future studies should study...
Research that has focused on the relationship between the Big Five personality dimensions and lucid dreaming frequency has been restricted to student samples. The present study included adolescents and adults (N = 1375). i.e., the sample included a large range of ages. Lucid dreaming was more strongly related to openness to experiences compared to previous findings. The small but significant...
Incorporation of details from waking life events into Rapid Eye Movement (REM) sleep dreams has been found to be highest on the night after, and then 5-7 nights after events (termed, respectively, the day-residue and dream-lag effects). In experiment 1, 44 participants kept a daily log for 10 days, reporting major daily activities (MDAs), personally significant events (PSEs), and major concerns...
There have been reports and claims in the psychotherapeutic literature that the consideration of recent dreams can result in personal realizations and insight. There is theoretical support for these claims from work on rapid eye movement (REM) sleep having a function of the consolidation of emotional memories and the creative formation of connections between new and older memories. To...
The ability to recall a dream upon waking up in the morning has been linked to a broad variety of factors such as personality, creativity, sleep behaviour and cognitive function. There have been conflicting findings as to whether dream recall is related more to the right or to the left hemisphere, and conflicting findings regarding the relationship of dream-recall frequency to handedness. We...
This paper addresses claims that dreams can be a source of personal insight. Whereas there has been anecdotal backing for such claims, there is now tangential support from findings of the facilitative effect of sleep on cognitive insight, and of REM sleep in particular on emotional memory consolidation. Furthermore, the presence in dreams of metaphorical representations of waking life indicates...
