We developed a dream content analysis system (DCAS) based on an artificial intelligence (AI) algorithm that was trained using a relatively large corpus of over 35,000 dreams. This sample of dreams were supplied by 424 female and 211 male users over 4 years who had posted them at the dream posting website and app Dreamboard.com. Building upon previous dream content ontologies developed by Hall,...
This chapter works towards a better understanding of the contribution made by the state of wakeful consciousness to the stream of consciousness over time. It does this through reflection on what is missing in certain cases of non-wakeful consciousness. Granting the assumption that dreaming is a mode of perceptual imagination, the chapter contrasts perceptual imagination in the wakeful condition...
Nightmare disorder affects approximately 4% of adults, occurring in isolation or as part of other disorders such as posttraumatic stress disorder (PTSD), and can significantly impair quality of life. This paper provides the American Academy of Sleep Medicine (AASM) position regarding various treatments of nightmare disorder in adults. A literature search was performed based upon the keywords...
Lucid dreams are dreams that involve awareness of dreaming while dreaming. As lucid dreaming is accompanied by heightened cortical activation, e.g., in the prefrontal cortex, it was speculated whether lucid dreaming interferes with the restorative function of sleep. Two cross-sectional studies have found inhomogeneous results regarding the relationship between lucid dream frequency and...
Chinese and Canadian people answered surveys in their native languages about their self-construal, media use history, and dreaming experiences. This included reporting a recent dream. The nightmare protection thesis was investigated. Sex was found to be modulated by culture in terms of the relationship between types of media used and negative dream content. This was particularly evident for men...
Vipassana meditation is characterized by observing bodily sensations, developing emotional and attentional stability, and promoting prosocial qualities. Whether these characteristics are also reflected in meditators’ dream content is not currently known. Evidence relating dream content with sleep-dependent learning is mixed: Some studies suggest that dreaming of a task is beneficial for...
Previous research on an efficacious cognitive-behavioral treatment for posttrauma nightmares and sleep disturbances (exposure, relaxation, and rescripting therapy; ERRT) has not tested the treatment in individuals with bipolar disorder. However, research suggests that individuals diagnosed with bipolar disorder are at increased risk for trauma exposure and development of posttrauma symptoms....
Anecdotal evidence indicates that supplementation with vitamin B6 (pyridoxine) before bed can enhance dream vividness and recall. In a single pilot study, Ebben, Lequerica, and Spielman (2002) found that vitamin B6 had a dose-dependent effect of increasing scores on a composite measure of dream vividness, bizarreness, emotionality, and color. The present research replicated this study using a...
Study objectives: Although nightmares have been associated with suicidal behavior beyond well-known risk factors, the association between nightmares and multiple suicide attempts remains largely unexplored. This study addressed this gap in the literature by examining whether nightmares differentiated between individuals who reported single versus multiple suicide attempts. The individual...
Dream recall ability can vary between and within individuals, dependent on a number of influencing factors, including personality dimensions, number of nocturnal awakenings, and attitudes towards dreaming. Only a few studies, however, consider the possible connection of dream recall ability to general waking memory ability, or the influence of being motivated to actively remember dreams. The...
Dreaming has often been viewed as a “mysterious” experience entirely distinct from waking cognition. An alternative view proposes that dreams are generated by the same fundamental processes that give rise to spontaneous thought during wakefulness. New evidence suggests that these processes include activity of the brain’s memory systems, supporting consolidation of newly encoded experience....
During dreaming, we experience a wake-like hallucinatory reality, however with restricted reflective abilities: in the face of a bizarre dream environment, we do not realize that we are actually dreaming. In contrast, during the rare phenomenon of lucid dreaming, the dreamer gains insight into the current state of mind while staying asleep. This metacognitive insight often enables the dreamer...

Although nightmares are common among trauma survivors, the posttrauma nightmare remains enigmatic and under-researched. For example, research has yet to examine if certain types of traumas may be more likely to create nightmares, which is this project’s primary question. Additionally, this project examined prevalence rates, gender differences, and the lifespans of posttrauma nightmares....

Imagery Rehearsal Therapy(IRT) is relatively a new evidence-based treatment for nightmare disorder patients. This is the first time investigating the treatment effects of IRT using fMRI. Based on past studies by Shen et al.(2016), nightmare disorder patients show increased regional homogeneity in both the anterior cingulate and inferior parietal lobule. This study used a one group pre-post...
The aim of this study was to compare the emotional content of dream reports collected at home upon morning awakenings with those collected in the laboratory upon early and late rapid eye movement (REM) sleep awakenings. Eighteen adults (11 women, seven men; mean age = 25.89 ± 4.85) wrote down their home dreams every morning immediately upon awakening during a 7-day period. Participants also...
Lucid dreaming is the phenomenon of dreaming while knowing that one is dreaming but the skills within the lucid dream, e.g., carrying out successfully pre-arranged tasks, vary considerably from dreamer to dreamer – even in frequent lucid dreamers. In order to measure inter-individual differences in lucid dreaming skills, a ten-item questionnaire was developed. The internal consistency was high....
Lucid Dreaming (LD) is awareness that one is dreaming, during the dream state. However, some define and assess LD relying also on controlling dream events, although control is present only in a subset of lucid dreams. LD has been claimed to represent well-being, and has even been used as a therapeutic agent. Conversely, LD is associated with mixed sleep-wake states, which are related to bizarre...
It is common to assume that dreamwork requires remembering and writing down many dreams. The good news is that you need not recall many of your dreams in order to derive transformative results from your dreamwork. As a matter of fact, Dream Sociometry can be effectively applied to waking events, which are, after all, subject to the same foibles of individual perception that we bring to dreams....
Study objectives: Sleep disturbances are common in United States military personnel. Despite their exposure to combat and trauma, little is known about nightmares in this population. The purpose of this study was to describe the prevalence and associated clinical and polysomnographic characteristics of nightmares in United States military personnel with sleep disturbances. Methods:...
Even though the common diagnostic criteria (ICSD-3, DSM-5) acknowledge that nightmares do not only contain anxiety/fear (definition of the ICD-10) but also other emotions such as grief, disgust, and anger, the definition of a nightmare still focuses on threats to survival, security, or physical integrity. However, empirical studies on nightmare content in larger samples are scarce. The current...
