Nightmares and suicide risk: broadening the therapeutic frame beyond Imagery Rehearsal Therapy.

Sleep plays an important role in affective processing and affect regulation during wakefulness. Dreaming-the subjective experiences occurring during sleep-has been suggested to reflect, or even contribute to, waking affect regulation. However, the role of dream affect in waking affect regulation has rarely been studied directly. Here, we investigated how dream affect relates to waking affect...

Abstract Introduction Exploding head syndrome (EHS) is characterized by the perception of a sudden loud noise or explosion in the head that occurs as the patient is falling asleep or waking up, typically associated with fear. The sensation is painless, lasts a few seconds, and may be associated with a flash of light or myoclonic jerk. Report of case(s) A 63-year-old-man with diabetes and...

Abstract Introduction Targeted Dream Incubation (TDI) is the process of giving an individual auditory cues (i.e., “think of a tree”) while they are falling asleep, with the goal of shaping dream content (into something such as a tree). Recent research has demonstrated TDI may be able to increase dream self-efficacy (DSE) and influence other mental health outcomes. Thus, our study explored how...

Abstract Introduction Nightmares are associated with more severe posttraumatic stress disorder (PTSD). The advent of large language models (LLM) offers unique advantages to efficiently code affective dream content over human methods, which can be resource intensive and prone to error. This study tested whether dream affect (DA), measured via self-report, human-rated narrative coding, and LLM...

Abstract Introduction Psychedelic use and interest in its therapeutic potential are rapidly increasing; yet its relationship with insomnia remains poorly understood. This study aims to estimate differences in insomnia severity by type of psychedelic consumed among a cohort of 18-to-35-year olds. Methods Data are from the Herbal Heart Study - Sleep Ancillary (N=100) cannabis consumers....

Nightmares are repeated and lengthy dreams, extremely dysphoric, with clear memory, typically involving life-threatening threats to safety or physical integrity. These nightmares lead to significant distress upon awakening and may substantially impact daytime functioning. Both the experience of these dreams and the sleep disruption produced by the ensuing awakening cause significant impairment...

Reactivation of waking neuronal activity during sleep holds a functional role in memory consolidation. Reprocessing of daytime memory in dreams might aid later memory performance in a similar way. Numerous findings hint at a link between dreaming and sleep-dependent memory processing; however, studies investigating day-residue incorporation in dreaming led to mixed results so far. In this...

The preoptic area of the hypothalamus is key for the control of sleep onset and sleep homeostasis. Although traditionally considered exclusively somnogenic, recent studies identified a group of preoptic glutamatergic neurons that promote wakefulness. Specifically, our previous investigations demonstrated that chemogenetic stimulation of glutamatergic neurons within the medial-lateral preoptic...

Abstract Introduction Lucid Dreaming, defined by a preserved sense of insight, thought, and control while dreaming, has been previously linked to internal locus of control, resilience and problem-solving. Lucid Dreaming may be important for individuals to exert a sense of agency in both dreams and daily life. This study therefore investigates how locus of control relates to lucid dreaming...

Abstract Introduction Dream reports provide unique insights into emotional processing during sleep. While self-reports are the gold standard for assessing dream affect, natural language processing (NLP) tools like ChatGPT may offer scalable alternatives. This study evaluated ChatGPT’s ability to estimate positive and negative affect from dream reports, comparing its performance against...

Abstract Introduction Dream recall frequency (DRF), or how often individuals remember and report dreams, is influenced by factors such as family dynamics, mental health, and cultural norms. Women tend to report higher DRF and greater distress from nightmares, while individuals with psychiatric conditions often exhibit reduced DRF. This study examined the relative contributions of childhood...

Abstract Introduction Recent studies and anecdotal reports suggest that sleep-onset hypnagogic dreams can contain creative insights, in some cases leading to Nobel prizes. While such reports are rare, targeted dream incubation (TDI) can induce dreams on pre-selected topics, such as “a tree,” in 70% of dream reports collected shortly after sleep onset, as well as a subsequent increase in...

Abstract Introduction Limited information is available to quantify hypnagogic/hypnopompic hallucination (HH) events people with narcolepsy (PWN) may experience. This post hoc analysis from the phase 3 REST-ON trial evaluated individual HH types. Methods REST-ON (NCT02720744) participants (age ≥16 years) with narcolepsy were randomized 1:1 to once-nightly sodium oxybate (ON-SXB) (week 1, 4.5 g;...

Abstract Introduction Research on psychedelic use and sleep satisfaction remains unclear despite increased use. This study examines the psychedelic use and sleep satisfaction among 18-to-35-year-olds enrolled in the Herbal Heart Study. Methods The exposure variables were lifetime self-reported use of any psychedelic (LSD, psilocybin, peyote, mescaline, ayahuasca/DMT) and psilocybin-alone. Sleep...

Abstract Introduction Targeted Dream Incubation (TDI) is the process of utilizing verbal cues (such as, “while you try to fall asleep, try and think of a tree”) during pre-sleep stages in order to directly shape dream content. Preliminary results have demonstrated that TDI may be able to increase dreaming self-efficacy (DSE). Our study aimed to replicate and extend initial findings by examining...

Abstract Introduction Approximately 12% of U.S. adults report having used any type of psychedelic at some point in their lives, making it one of the most widely used recreational drugs. There exists a need for a better understanding of the consequences of use on objective sleep habits. Research on psychedelics effects on sleep indicate increased sleep duration, increased REM latency, and...

One in ten US Veterans endorse trauma-related nightmares in their lifetime. Imagery rehearsal therapy is an effective and time-efficient therapy which is not widely accessible. We sought to evaluate if a group format could improve access to treatment. This quality improvement project utilized Plan-Do-Study-Act methodology to evaluate impact on access to care by creating a group format for...

Research has begun to identify self-efficacy as a crucial variable related to positive treatment outcomes. For treatments targeting nightmares, self-efficacy related to dreaming (DSE) has been proposed to be a key mechanism of change. Additionally, a robust amount of research exists that links nightmares to suicide, suggesting that mechanisms related to trauma-related nightmares may also be...

Disorders of arousal (DoA) are diagnosed on the basis of clinical criteria, including inappropriate or absent responsiveness to communication attempts. Surprisingly, the ability of patients to interact with others during DoA episodes has not been systematically investigated. To address this gap, we conducted three studies. First, we used a retrospective questionnaire to assess verbal...

Mindfulness-based interventions (MBI) have been shown to improve psychosocial functioning in medical populations but have not been studied in narcolepsy. This study examined the feasibility and acceptability of an MBI that was adapted for narcolepsy, including three variations in program length. Adults with narcolepsy (N = 60) were randomized to MBI groups of varying durations: brief (4 weeks),...

Abstract Introduction Dreaming has been theorized to facilitate fear extinction learning in a manner akin to desensitization therapy. A testable hypothesis from this theory is that the experience of fear in dreams leads to lower subsequent daytime negative affect. This study employed a novel natural language processing tool and multilevel modeling to test whether fear in dreams led to...
