Nightmare disorder (NDO) is a significant but often under-recognized condition, especially within the military population. We previously reported that 31.2% of patients referred to our military sleep disorders center have NDO, yet only 3.9% were referred for NDO. Despite the general population’s NDO prevalence (2-8%), our center had no referrals for NDO from June 1 to August 31, 2024. This...

Fear of sleep engenders arousal at bedtime that can promote nightmares. Living in disadvantaged neighborhoods with high rates of community violence may exacerbate fear of sleep and in turn increase nightmare risk. We tested fear of sleep among acute trauma patients as a prospective predictor of nightmares, and whether exposure to community violence moderated this relationship. Patients...

A robust body of research has linked nightmares to suicide. For example, research has found that nightmares predict suicidal ideation above and beyond other mental health symptoms (such as depression and post-traumatic stress disorder) and that treating nightmares may indirectly decrease the risk of suicide. Considering the established link between nightmares and suicide, our goal was to...

Nightmares and insomnia commonly co-occur with Posttraumatic Stress Disorder (PTSD), with 70% to 91% of individuals with PTSD reporting chronic nightmares and insomnia. Evidence suggests that even gold standard treatments for PTSD (such as Prolonged Exposure, PE) and insomnia (CBT-I) individually may not fully resolve nightmares. Our study presents secondary analyses of a randomized controlled...

Nightmare Disorder (NDO) is estimated to impact at least 4% of the US adult population yet is reported to be much higher among service members (SMs). Our Center has previously reported 31.2% of referred SMs had probable NDO based on screening measures, yet only 3.9% reported nightmares as a reason for evaluation. No quality measures report on the rate of confirmed diagnosis, and more...

Many studies involving the relationship between personality and nightmare frequency (NF), common in cross-sectional data, have only looked at neuroticism in isolation, assumed a linear relationship, or did not include nightmare disorder index (NDI) to determine if personality traits might predict NDI over NF. While neuroticism is the personality trait most commonly associated with nightmares,...

Dream recall has high individual variability affected by a wide spectrum of methodological variables. The possibility that multiple dreams are typically experienced each night has received minimal study. 51 subjects were recruited from college psychology classes (35 F/16 M, mean age 22.2). The intake questionnaire queried subject dream recall varying from no dream recall=1, to multiple dreams...

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...

An epidemiological study conducted by the Sleep Institute in 2007 revealed that 44.8% of the population in São Paulo exhibited symptoms of insomnia, with women being disproportionately affected (32%). Considering a global adaptation towards utilizing technology for health services, the present study evaluated the effects of an online meditation program on women with insomnia. The study was a...

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...

Despite advances in sleep and dream science via neuroscientific methods, self-reported diary data (e. g. dream journals) remain indispensable for capturing theory-relevant phenomenological aspects of dreams including their emotional content [1, 2]. Manual annotation of such data; however, is time-intensive and typically requires human coders to be trained to reliability. To circumvent these...

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...

Abstract Introduction Completing a learning task just before sleep often induces task-related dreams. This is thought to reflect the consolidation of recently formed memories in the sleeping brain. However, this literature has focused almost exclusively on how recent experiences newly introduced before sleep are incorporated into dreams. It is unknown whether and how remote memories may also be...

Few providers are trained to deliver Cognitive Behavioral Therapy for Nightmares (CBT-N) despite the impact of nightmares on physical and mental health. Reduced access to treatment is partially due to limited training opportunities. Web-based training resources are valuable because they are easily accessible, are cost-efficient, and can be reviewed by providers as needed. This presentation...

Abstract Introduction Sleep Paralysis (SP) is a sleep-disturbing experience of muscle atonia while conscious, creating an in-between sensation of wakefulness and dissociation during REM sleep. During SP, one can experience hypnagogic and hypnopompic hallucinations, which may cause feelings of terror and fear. These feelings affect the overall well-being of the experiencers and may impact other...

According to the continuity hypothesis, dreams reflect waking life experiences. Metacognition, the awareness of one’s thought processes, is minimal during typical dreaming but is assumed to be greater during lucid dreams, when the dreamer is aware they are dreaming and can sometimes control dream content. Therefore, one hypothesis is that lucid dreams may be more continuous with waking life...

Abstract Introduction We report the electroencephalography (EEG) changes observed in a case of sleep paralysis. Methods We present the case of a 15-year-old boy with recurrent isolated sleep paralysis. As part of the diagnostic evaluation, the patient underwent overnight polysomnography (PSG) and subsequently, a multiple sleep latency test (MSLT). During the MSLT, the patient experienced sleep...

Abstract: Introduction: Decoupling patterns of sleep and wake from underlying circadian oscillations is associated with poor sleep health. While this has been studied with respect to shift work, it is unclear if minor variations in normative sleep/wake patterns affect the restoration of cognitive function during sleep intervals while controlling for total sleep time. It is commonplace to adhere...

Rapid Eye Movement (REM) Sleep Behavior Disorder (RBD) is a parasomnia occurring during REM sleep, characterized by loss of normal REM sleep atonia and dream enactment behaviors. The majority of patients diagnosed with idiopathic RBD will develop an alpha-synucleinopathy neurodegenerative disease, which can complicate the treatment of RBD. First-line treatment with high-dose melatonin or...

Sleep paralysis is a condition that has been on the rise in recent years, occurring during the pre or post sleep stages. While there is no known direct cause of sleep paralysis, studies have shown a number of potential causes, including poor quality of sleep, alcohol use, exposure to stressful events, anxiety disorders, and a family history of the illness. The purpose of this study was to...

Sleep-related hallucination (SRH) is a parasomnia that may be encountered in the form of altered dream mentation in α-synucleinopathies, particularly in the setting of dementia with Lewy bodies (DLB). Visual hallucinations (VH) are complex, well-formed, episodes that represent a core diagnostic criterion for DLB. We report a patient who presented with REM sleep behavior disorder (RBD), VH, and...
