Nightmares have been tied to a myriad of adverse mental health outcomes and are known to persist after treatment of other concerns such as posttraumatic stress, depression, and anxiety. When reaching clinical levels, nightmare disorder is known to effect 2-6% of the general population, Although many treatments exist for nightmare disorder and posttraumatic nightmares, Imagery Rehearsal Therapy...

Abstract: Introduction: Nurses report a higher prevalence of posttraumatic stress disorder (PTSD) than the general population, and approximately 18% of nurses report having depression. Nightmares are a common symptom of PTSD, and both nightmares and PTSD are correlated with depression. Nightmares may represent a possible clinical target for improving outcomes in both disorders. This study...

Abstract Introduction In the James A. Haley Veterans Administration (JAHVA) Vista database, the ICD-9 code 307.47 for Nightmare disorder (ND) is infrequently used and appears independently of codes for PTSD. We wanted to determine if certain drugs that may affect sleep are associated with ND. Methods All patients with ND visiting JAHVA between 2007 and 2011 were selected along with control...

Lucid dreaming (being aware that one is dreaming) is typically a positive experience that may enhance positive mood even after waking. There is concern, however, that lucid dreaming may interfere with sleep quality. In the current experiment, participants practiced common lucid dream induction techniques over the course of a week, and kept a daily sleep and dream diary. The study objective was...

Abstract Introduction Nightmares can cause poorer sleep quality. Various mechanisms have been explored as potential treatments for nightmares, including mindfulness practices and lucid dreaming. Presently, little literature has looked at the interaction effects between mindfulness and lucid dreaming to reduce nightmare distress. Methods A sample of 275 individuals was recruited from both the...

Neuroscience and psychology agree that dreaming helps to cope with negative emotions and learn from experience. The current global threat related to the COVID-19 pandemic led to widespread social isolation. Does dreaming change and/or reflect mental suffering? To address these questions, we applied natural language processing tools to study 239 dream reports from 67 individuals either before...

IntroductionLucid dreaming (LD) started to be scientifically investigated through instructingdreamers to move their eyes as soon as they become lucid (Hearn, 1978; Laberge et al.,1981). LD signaling through pre-agreed eye movements (PAEM) is possible becauseeye muscles are exempt from the muscular atonia that accompanies REM sleep(Aserinsky and Kleitman, 1953; Jouvet, 1962). In addition, it is...

Pharmacological treatment with prazosin and psychological treatment with imagery rehearsal therapy (IRT) are the two main treatments of posttraumatic nightmares. The American Academy of Sleep Medicine task force recently listed IRT as the recommended treatment for trauma-related nightmares and changed the recommendation of prazosin to 'may be used'. This new recommendation was based on a single...

Nightmares are scary or disturbing dreams which are associated with negative feelings, such as fear, terror or disgust. These feelings oftentimes awake the dreamer, who can easily recollect the content of the nightmare. Nightmares are not necessarily a symptom of a disease. Moreover, nightmares with little emotional response are experienced by almost all people once in a while without any risk...

A long noted hypothesis is that mechanisms of dreaming play a role in psychotic hallucinations. One challenge for this hypothesis is that while psychotic hallucinations primarily are auditory, dreaming most characteristically is visual. At the same time, previous studies have not explicitly examined auditory impressions in dreaming. Here, we mapped the prevalence and characteristics of auditory...

REM periods with lucid dreaming show increased brain activation, especially in the prefrontal cortex, compared to REM periods without lucid dreaming and, thus, the question of whether lucid dreaming interferes with the recovery function of sleep arises. Cross-sectional studies found a negative relationship between sleep quality and lucid dreaming frequency, but this relationship was explained...

Accurate localization of complex human experiences such as emotions, dreaming, creativity, and consciousness to specific cerebral structures or neural networks has remained elusive despite technological advances. We report the use of acute deep brain stimulation (DBS) to evoke behavioral and emotional effects by applying electrical stimulation (ES) at various voltage strengths to the...

Most people experience lucid dreams (LDs), which are dreams in which the dreamer is conscious and able to perceive vivid perceptions. There are many ways to induce LDs, but their levels of efficiency are far from satisfactory. In this study, we analyze the efficiency of an LD method that was tested in commercial events with hundreds of groups over 12 years. The main feature of the method is...

The various ways schools of psychotherapy relate to dreams have been marked by isolationism and mutual conflict rather than self-examination and then integrating the discoveries and methods of other schools. Jung's method was in opposition to Freud's psychoanalysis. Existential psychology was dismissive of Freud's and Jung's discoveries, while cognitive dream interpretation and cognitive...

Presented is an implementation of the SALAD algorithm for dream content analysis through word searching. Helper functions for constructing initial seed word dictionaries are provided in "hyponym_dictionary.py" which will also be used to construct the dictionaries from the seed words. "read_csv.py" reads and pre-processes the dream reports into a dictionary that captures the linguistic features...

Frequent nightmares have a high prevalence and constitute a risk factor for psychiatric conditions, but their pathophysiology is poorly understood. Our aim was to examine sleep architecture and electroencephalographic markers-with a specific focus on state transitions-related to sleep regulation and hyperarousal in participants with frequent nightmares (NM participants) versus healthy controls....

The sleep paralysis nightmare has been reported from antiquity to modernity across manifold cultures. Many people who experience nocturnal assaults by dark entities, demons, hags, or incubi during sleep paralysis ascribe them to evil spirits with varying degrees of malevolence. The majority report the episodes as terrifying, mysterious, and uncanny. Known in the neurocognitive literature as...

Previous research introduced the Nightmare Proneness Scale (NPS) as a measurement for nightmare proneness, the trait-like disposition to experience frequent nightmares. However, outside predicting nightmares, little is known about the structure of the scale or relationships of its facets with nightmares. The factor structure of the NPS and the scale's statistical independence from psychological...

The α1-adrenergic antagonist prazosin has showed good effect against posttraumatic stress disorder-related nightmares in several randomized controlled trials. The α1-adrenergic antagonist doxazosin, which has a longer half-live than prazosin, has received far less attention in the treatment of such nightmares. Here, we report a case of a patient suffering from severe nightmares following an...
