Abstract: Introduction: Dream content is typically measured using self-reports which draw heavily on psychoanalytic theory. There is a need for a modern, reliable, validated, and comprehensive measure of dream content and experience. The DIAMONDS taxonomy has been developed and extensively validated by social/personality psychologists to assess psychologically salient features of waking...

In particular, long-term and persistent psychopathological detriments were observed in those who were infected by acute forms of the virus and need specialistic care in the Intensive Care Unit (ICU). Imagery rehearsal therapy (IRT) has shown promising results in managing nightmares of...

Sleep is a fundamental biological function that is present in all tested vertebrates and most invertebrates....

Sleep paralysis and lucid dreams are two states of consciousness that are connected to REM sleep but are defined by higher awareness in contrast to regular REM sleep. Despite these similarities, the two states differ widely in their emotional tone and their perceived controllability. This review aims to summarize the current research containing sleep paralysis and lucid dreams. However, given...

No specific pharmacological treatment for PTSD-related nightmares is yet approved. Preliminary clinical data indicate that cannabinoid agonists can improve nightmares and overall PTSD symptoms in patients with...

We conducted an online study in healthy participants (n=514) with DP traits to investigate and quantify the subjective experience of body and self during waking and dreaming, as the vast majority of previous studies focussed on waking...

Abstract Introduction Observational research demonstrates a strong association between nightmares, insomnia, and sleep apnea in veterans with posttraumatic stress disorder (PTSD), supportive of the notion of a “complex sleep disturbance”. Relations between sleep disturbances and PTSD are often bi-directional and disturbed sleep affects non-sleep PTSD outcomes. We aimed to examine relationships...

The incidence and clinical significance of nightmares is difficult to estimate due to varying criteria across studies. The Nightmare Disorder Index (NDI) is a validated measure to evaluate nightmare disorder. However, there is no measure to differentiate trauma-related nightmares compared to trauma associated sleep disorder (TSD), a unique REM parasomnia. The objectives of this study were to...
