The neural mechanisms underlying lucid dreaming have recently been investigated using brain imaging techniques such as electroencephalography and functional magnetic resonance imaging, which produce insightful but merely correlative results. We propose that research on the neurophysiology of lucid dreaming, for instance concerning the exact relationship between the dorsolateral prefrontal...

Nightmares, distressing dreams that primarily arise from REM sleep, are prevalent among the general population and even more so among clinical populations. The frequency of nightmares and related nightmare distress are linked to both sleep disturbance and waking psychopathology. Based on the extant evidence, nightmares appear to be particularly relevant to posttraumatic stress disorder, and may...

This study investigated the effectiveness of a psychotherapeutic treatment for nightmares that was adapted for 6- to 11-year-old children from imagery rehearsal therapy. Ten child-mother dyads took part in a 3-session, 8-week treatment protocol.

AbstractAlthough the concept of ‘lucid dreaming’ was first coined by Frederik Willems van Eeden, a Dutch psychiatrist, and introduced at the meeting of The Society for Psychical Research held on 22 April 1913, the phenomenon of lucid dreaming was already known in earlier historical periods and its descriptions can be found in writings of Aristotle. However, modern lucid dreaming research was...

Insomnia and nightmares are hallmarks of posttraumatic stress disorder (PTSD). Sleep disturbances in PTSD negatively impact clinical course and functioning. In this open clinical trial, the preliminary effects of a combined treatment for insomnia and nightmares in combat veterans with PTSD were assessed. Ten combat veterans participated in a 10-session group treatment combining...

Dreaming has fascinated and mystified humankind for ages: the bizarre and evanescent qualities of dreams have invited boundless speculation about their origin, meaning and purpose. For most of the twentieth century, scientific dream theories were mainly psychological. Since the discovery of rapid eye movement (REM) sleep, the neural underpinnings of dreaming have become increasingly well...

Dreaming is commonly reported after propofol-based sedation. We measured the incidence of dreaming and bispectral index (BIS) values in colonoscopy patients sedated with combinations of propofol, midazolam and fentanyl. Two hundred patients presenting for elective outpatient colonoscopy were sedated with combinations of propofol, midazolam and fentanyl. BIS was monitored throughout the...

A new experimental paradigm called "Early-Night Serial Awakenings" (ENSA) was explored to find out its strengths and weaknesses for psychophysiological studies of NREM sleep dreaming. Five participants spent 20 experimental nights in the sleep laboratory, and were serially awakened with approximately 24-minute intervals during Stages 2 and 3 of NREM sleep. As a total, 164 awakenings were...

This paper systematizes the word search potential of DreamBank.net (Domhoff & Schneider, 2008a, 2008b) by formulating and testing a set of word strings that can be used as default analytic categories in future investigations. The word strings are applied to the 981 dream reports of college students gathered by Hall and Van de Castle (1966) and the 136 dream reports of an 80-year old male...
