“…That dream rebound led to higher pleasantness scores in both conditions, and especially for those that failed to suppress unpleasant thoughts, suggests that dreaming of the thought led to amelioration of unpleasantness and/or increased pleasantness. This is in line with Fading Affect Bias theory; the reduction in negative response to unpleasant memories may occur during sleep, as reflected in dream content (Horton & Malinowski, ). When this does not take place during sleep, affect may remain negative.…”

The effects of dream rebound: evidence for emotion‐processing theories of dreaming

Suppressing thoughts often leads to a “rebound” effect, both in waking cognition (thoughts) and in sleep cognition (dreams). Rebound may be influenced by the valence of the suppressed thought, but there is currently no research on the effects of valence on dream rebound. Further, the effects of dream rebound on subsequent emotional response to a suppressed thought have not been studied before. The present experiment aimed to investigate whether emotional valence of a suppressed thought affects dream rebound, and whether dream rebound subsequently influences subjective emotional response to the suppressed thought. Participants (N = 77) were randomly assigned to a pleasant or unpleasant thought suppression condition, suppressed their target thought for 5 min pre‐sleep every evening, reported the extent to which they successfully suppressed the thought, and reported their dreams every morning for 7 days. It was found that unpleasant thoughts were more prone to dream rebound than pleasant thoughts. There was no effect of valence on the success or failure of suppression during wakefulness. Dream rebound and successful suppression were each found to have beneficial effects for subjective emotional response to both pleasant and unpleasant thoughts. The results may lend support for an emotion‐processing theory of dream function.

“…REM sleep’s physiological and psychological features also have been associated with more complex functions. For example, REM sleep has been suggested to heighten autobiographic memory (Horton and Malinowski, 2015; Malinowski and Horton, 2015) and to render previously encoded memories more distinct through its hyper-associative dreaming state (Llewellyn, 2013; Llewellyn and Hobson, 2015). Also, it is thought to incorporate these previously encoded memories into a broader vital context, thus embedding them in consolidated residuals of hypotheses, emotions, basic needs, and individual genetic traits (Kirov, 2013).…”

Opposite Impact of REM Sleep on Neurobehavioral Functioning in Children with Common Psychiatric Disorders Compared to Typically Developing Children

et al. 2017

Rapid eye movement (REM) sleep has been shown to be related to many adaptive cognitive and behavioral functions. However, its precise functions are still elusive, particularly in developmental psychiatric disorders. The present study aims at investigating associations between polysomnographic (PSG) REM sleep measurements and neurobehavioral functions in children with common developmental psychiatric conditions compared to typically developing children (TDC). Twenty-four children with attention-deficit/hyperactivity disorder (ADHD), 21 with Tourette syndrome/tic disorder (TD), 21 with ADHD/TD comorbidity, and 22 TDC, matched for age and gender, underwent a two-night PSG, and their psychopathological scores and intelligence quotient (IQ) were assessed. Major PSG findings showed more REM sleep and shorter REM latency in the children with psychiatric disorders than in the TDC. Multiple regression analyses revealed that in groups with developmental psychopathology, REM sleep proportion correlated positively with scores of inattention and negatively with performance IQ. In contrast, in the group of TDC, REM sleep proportion correlated negatively with scores of inattention and positively with performance IQ. Whilst shorter REM latency was associated with greater inattention scores in children with psychopathology, no such an association existed in the group of TDC. Altogether, these results indicate an opposite impact of REM sleep on neurobehavioral functioning, related to presence or absence of developmental psychiatric disorders. Our findings suggest that during development, REM sleep functions may interact dissimilarly with different pathways of brain maturation.

“…Dream ruminations rely upon two parallel processes: fragmenting memory images to better understand them and uniting these images in a narrative‐like montage (see also Horton and Malinowski , 4). Fragmentation begins with Like‐but ambiguity in which one sees a difference between an original and a copy—in Clarence's dream, the beast who is “similar to” a werewolf.…”

“…You could tell he didn't like it but he kept on drinking. Robert's three heads visually conceptualize his incompatible “sides,” incompatibility that is played out in the dream montage. While dream researchers sometimes take bizarreness as a trope for all dream discontinuities (Horton and Malinowski , 4; States, ), I see bizarre images as a specific way of creating ambiguity. Bizarre images compel one to entertain two images at once—the unexpected dream image and an implied expected image.…”

Ambiguity as Dream Mentation: Supermasculinity and Ambivalence in American Dreams

Ambiguity, this paper argues, is not merely a property of dream imagery, but ignites a process that is dreaming thinking. When images are ambiguous, the mind cannot fix on a single meaning. Hence dream ambiguity catalyzes a play of possible meanings that implicitly raises questions, not only about personal memories but also about those cultural models that these memories evoke. Dream thinking, then, renders people's ongoing subjective reactions to culture into images. Through data from a 2004 to 2009 study of Northwest American student dreams and life histories, I propose that people think within dreams by representing daily ambivalences as visual ambiguities. Excerpts from this dream study illustrate seven types of visual ambiguity in dreams. Implicit in this taxonomy is a method of cultural dream interpretation that I present through an analysis of a full dream from a young man, Clarence. Through this analysis I show how ambiguities in Clarence's dream represent his ambivalence about an American masculinity model—one that may underlie the school shootings that are now so common in the United States.
