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...

In order to ensure robust relationships between the dependent and independent variables in clinical dream/nightmare studies, the major factors which influence the frequency of reported dreams must be controlled. This article sets out methodological recommendations to both researchers seeking to ensure the equivalence of experimental groups of participants in group-matching designs, and to...

In the current study, we aimed to investigate the EEG correlates of dream recall (DR) monitoring both the homeostatic and state-trait like factors. We assessed the influence of the time of night on the EEG correlates of DR from REM sleep. Specifically, we tested the continuity-hypothesis (on the theta EEG band) and the activation-hypothesis (on the delta and beta bands). Twenty-seven subjects...

It is difficult to assess recollection of dreams by reliability of what happened despite the fact that the opposition “reality – dream” is considered a cultural universal. Such a task grows even more complex as one turns to recollection of so called lucid dreams. The article covers different types of messages published on the Dream Hackers forum. That online community is the largest...

The Dream Catcher test defines the criteria for a genuine discovery of the neural constituents of phenomenal consciousness. Passing the test implies that some patterns of purely brain-based data directly correspond to the subjective features of phenomenal experience, which would help to bridge the explanatory gap between consciousness and brain. Here, we conducted the Dream Catcher test for the...

Focusing on lucid dreaming, this paper examined relationships between dissociated experiences related to rapid eye movement (REM) sleep (lucid dreaming, nightmares, and sleep paralysis), reality testing, and paranormal experiences/beliefs. The study comprised a UK-based online sample of 455 respondents (110 males, 345 females, Mean age = 34.46 years, SD = 15.70), who had all previously...

Lucid dreaming refers to a dream state characterized by the dreamers' awareness of being in a dream and being able to volitionally control its content. The aim of this study was to describe and model neurophysiological evidence for the seven awareness criteria of lucid dreaming based on those proposed by Paul Tholey. Each of the awareness criteria was analyzed separately with regard to its...
