Background: Nightmare disorder (NDO) is a clinically under-recognized sleep disorder within the military population. We have previously reported that 31.2% of patients referred to our sleep disorders center incidentally had probable NDO, yet only 3.9% were specifically referred for NDO. Under-recognition and therefore under-treatment of NDO negatively impacts patients' health and military...

Sleep-related out-of-body experiences (OBEs) occupy an ambiguous position between sleep paralysis and lucid dreaming. OBEs are often considered part of the vestibular-motor component of sleep paralysis, but they also share features with lucid dreaming, including vivid internally generated experience, heightened awareness, and perceived agency. Here, we examined whether the emotional composition...

Introduction: The return to normal life following the COVID-19 pandemic was evaluated in terms of anxiety upon awakening, sleep quality indicators, and dream characteristics. Methods: The sample comprised 394 women and 107 men who completed an online self-report questionnaire between August 15, 2022, and December 8, 2022 about their sleep and dream experience from the previous night....

Targeted dream incubation (TDI) is a highly effective method for eliciting hypnagogic dreams related to specific topics through the presentation of verbal prompts and serial awakenings at sleep onset. In this pilot study, we tested whether TDI at sleep onset can effectively direct dream content in subsequent rapid eye movement (REM) sleep. We allowed participants a daytime nap opportunity...

Abstract Nightmare disorder is historically conceptualised as a rapid eye movement (REM) sleep parasomnia, but evidence also points to altered non-rapid eye movement (NREM) sleep physiology. Here, in a retrospective case-control study, we analysed overnight polysomnography from 26 adults with nightmare disorder and 32 controls using a harmonised event-based EEG pipeline. Nightmare disorder...

An essay on sleep as the separation of mind and body, written by someone who does not get much of it. It moves from a joke in a cartoon to the genetics of familial natural short sleep and the contemplative traditions that train the mind to stay awake while the body rests, and it is careful to say which of those the author is standing in — neither. The sleep genetics describes a rare inherited...

Background: Motor learning in competitive sport relies not only on physical practice but also on the offline reorganisation of memory traces during sleep. Waking motor imagery is a recognised ergogenic adjunct, while recent work suggests that mental rehearsal may be extended into the sleeping brain through lucid dreaming, a state in which the dreamer becomes aware of dreaming while remaining...

Background: Traumatic nightmares are a core feature in adolescents with complex PTSD (CPTSD) exposed to early and repeated trauma, maintaining hyperactivity and dysregulation. Despite their prevalence and functional impact, targeted treatments for youth remain scarce. Imagery rehearsal therapy (IRT) is a brief cognitive-behavioral intervention effective in adults, but evidence in adolescents...

Sleep disorders and nightmare disturbances challenge clinical assessment due to subjective self-reporting and lack of quantitative precision. This work presents DreamSense, a multi-task deep learning framework using electroencephalography (EEG) biomarkers that classify dream states on three independent tasks: occurrence detection, emotional sentiment, and nightmare intensity. Via systematic...

ABSTRACT Although about 5% of the German population report having nightmares at least once a week, nightmares are inadequately diagnosed and treated. We therefore examined how people in the general population cope with nightmares in everyday life. The present study aimed to examine the influence of Big Five personality traits on nightmare‐coping behaviour. In an online survey of 411...
