Investigate the efficacy of nabilone capsules (NAB) in reducing the frequency and intensity of nightmares in subjects with PTSD. Canadian male military personnel with PTSD, who despite standard treatment continued to experience trauma-related nightmares, received double-blind treatment with 0.5mg NAB or placebo (PBO), and then titrated to the effective dose (nightmare suppression) or reaching a...
Using the Neuroadaptagen KB200z™ to Ameliorate Terrifying, Lucid Nightmares in RDS Patients: the Role of Enhanced, Brain-Reward, Functional Connectivity and Dopaminergic Homeostasis.
Studies investigating the prevalence of nightmares have generally found higher frequencies in studies using daily logbooks or diaries compared to retrospective reports, raising the question as to whether retrospective questionnaires lead to an underestimation of nightmare frequency, possibly due to the suppression of the frightening nightmare experience or if the diary enhances recall. In this...
AbstractPrevious research has indicated that nightmares might be a common problem for people with psychotic symptoms. Furthermore, more distressing nightmares have been associated with higher levels of delusional severity, depression, anxiety, stress and working memory. However no known research has investigated the use of nightmare treatments in those with symptoms of psychosis. This study...
Dreaming represents a peculiar form of cognitive activity during sleep. On the basis of the well-known relationship between sleep and memory, there has been a growing interest in the predictive role of human brain activity during sleep on dream recall. Neuroimaging studies indicate that rapid eye movement (REM) sleep is characterized by limbic activation and prefrontal cortex deactivation. This...
We examined the question whether the role of EEG oscillations in predicting presence/absence of dream recall (DR) is explained by "state-" or "trait-like" factors. Six healthy subjects were awakened from REM sleep in a within-subjects design with multiple naps, until a recall and a non-recall condition were obtained. Naps were scheduled in the early afternoon and were separated by 1 week....
Sleep and dreaming do not serve a single biological function, but are multifunctional. Their functions include memory consolidation and integration, emotion regulation, creativity and problem solving, and preparation for waking life. One promising level of description is that of dreaming as a virtual reality: The dreamer interacts with a simulated environment including other simulated avatars....
Lucid dreaming may be defined as the conscious awareness that one is dreaming while dreaming. Instead of incorrectly assuming that one is awake, the dreamer gains insight about her or his real state of consciousness. Lucid dreaming is rare and evanescent, which probably accounts for lingering doubts about its veracity and for its marginalization in science. The purpose of this paper is to...
The prediction of suicidal intent remains a clinical problem. This presentation illustrates that a distinction may be made between the manifest dream reports of patients who are potentially or acutely suicidal and those who are not. A review of the literature reveals that the manifest dream reports of clinically depressed, non-suicidal individuals differ from those who are depressed and acutely...
Shamanism is a worldwide social phenomenon consisting of a set of practices (e.g., ritualistic drumming, sensory deprivation, the ingestion of entheogens and dream incubation) designed to obtain knowledge from alternative realities for the purpose of benefiting one's social group. The aim of this paper is to provide a cross-cultural exploration of dreaming in the context of shamanism. We...
