Nightmare disorder is a mental health condition characterized by repeated occurrences of extended, well-remembered, dysphoric dreams, often involving themes of threat, that result in awakening from sleep and significant distress and impairment. Research points to factors such as traumatic experiences, childhood adversities, suppression of thoughts, maladaptive beliefs, other medical conditions...
Aim: Suvorexant is an orexin receptor antagonist (ORA) for the treatment of insomnia. The antagonistic action of suvorexant on orexin receptors is associated with an increase in rapid eye movement (REM) sleep, which can potentially lead to nightmares depending on the patient's condition. However, the precise risk factors for nightmares among patients taking ORAs, such as suvorexant, have yet to...
Abstract Lucid dreams are a distinctive and intriguing phenomenon where subjects apparently possess, inter alia, conscious knowledge that they are dreaming while they are dreaming. I here develop and defend a new model of lucid dreaming, what I call the ‘Dyadic Model’, according to which lucid dreams involve the tokening of both dreaming and non-dreaming states. The model is developed to...
Although numerous individual factors influencing dream content have been explored, research on the link between sexual orientation and dreaming remains limited. This study examined this relationship among 119 German-speaking men (mean age = 31.97 years), including 55 homosexual and 64 heterosexual participants. Participants completed a questionnaire on their waking life sexuality and dreams and...
Introduction: The role of neuroticism in the relationship between nightmare characteristics (e.g., frequency and replicativity), and nightmare-related suffering, i.e., nightmare-related distress and impairment after awaking, is still to be explored. Methods: In a sample of 346 soldiers (mean age 33.95 years, 13.9% females) who experienced at least one traumatic event (47.0% having a formal...
This study developed, designed, and demonstrated a low-arousal clock face intended to reduce Time Monitoring Behavior (TMB) stimuli. The research discussed the interrelationships of the five senses during the sleep cycle, identifying external stimuli suitable for time interface design. This aims to resolve the contradiction of using smartwatches to monitor sleep while the readily accessible...
Lucid dreaming is defined as achieving conscious awareness of dreaming while still asleep. Lucid dreaming can manipulate scripts and is known as a non-pharmacological treatment for nightmares caused by psychological stress. This study examined the relationship between the type of lucid dreaming (self-awareness and script control), Big Five, and stress coping styles using a web-based survey of...
ABSTRACT Background: Research suggests trauma-related nightmares (TRNs) during the acute aftermath of trauma may contribute to posttraumatic stress disorder (PTSD). However, it is unknown who is most vulnerable to TRNs, which is critical to identify at-risk patients toward whom early nightmare-focused treatments can be targeted to prevent PTSD. Objective: We tested trauma type (interpersonal...
Objective: Bad dreams and nightmares can have a strong psychological impact. However, although the scientific literature points in the direction of an established association between nightmares and psychopathology, many of the studies investigating these links have been carried out on a general population. This systematic literature review aimed to identify studies that have used a sample from...
In a lucid dream one is aware that one is dreaming. However, the degree of awareness andcontrol someone typically possesses in their lucid dreams, summarized as an individual’s luciddreaming skills, varies. Previous research has identified both the frequency of lucid dreamsand age as predictors. In this study, we explored the relationship between lucid dreaming skillsand age, dream recall,...
