We examined the relationships between recall of dreaming during anesthesia and postoperative nausea and vomiting (PONV). We found a relationship between PONV within 24 h and age <50 years, use of postoperative epidural analgesia with morphine, and female gender. We also found a relationship between PONV lasting more than 24 h and dream recall. As serotonin plays an important role for both...

Background and Objectives: Nightmares are defined as disturbing mental experiences that generally occur during REM sleep and often result in awakening. Even though about 5% of the general population suffers from nightmares, little is known about seeking professional help in this patient group.

Although a growing body of research indicates that frequent nightmares are related to impaired sleep regulation, the pathophysiology of nightmare disorder is far from being fully understood. We examined the relative spectral power values for NREM and REM sleep separately in 19 individuals with nightmare disorder and 21 healthy controls, based on polysomnographic recordings of the second nights'...

Unique dream patterns are related to psychopathological distress in adults. In adolescence, this was investigated almost exclusively regarding nightmares. This longitudinal study examines developmental trajectories of various adolescent‐reported dream patterns, and their associations with parent‐reported psychopathology (internalization and externalization problems) in early adolescence....

The hypothesis that dreaming is involved in off-line memory processing is difficult to test because major methodological issues have to be addressed, such as dream recall and the effect of remembered dreams on memory. It would be fruitful--in addition to studying the ancient art of memory (AAOM) in a scanner--to study the dreams of persons who use AAOM regularly.

The aim of this study was to investigate whether auditory presentation of a story during general anaesthesia might influence stress hormone changes and thus affecting dream recall and/or implicit memory. One hundred and ten patients were randomly assigned either to hear a recording of a story through headphones or to have routine care with no auditory recording while undergoing laparoscopic...

Lucid dream and nightmare frequencies vary greatly between individuals and to assess these differences reliable instruments are needed. The present study aimed to examine the reliability of eight-point scales for measuring lucid dream and nightmare frequencies. The scales were administered twice (with a four-week interval) to 93 sport students. A re-test reliability for the lucid dream...

In this article, the authors provide information on key characteristics of imagery rehearsal treatment protocols and examine the quality of reporting of randomized controlled and uncontrolled trials of imagery rehearsal for treating posttraumatic nightmares. Using a reliable and valid scale, two independent psychologists rated 16 trials. Most reports provided insufficient information on a range...

Even when we are ostensibly doing "nothing"-as during states of rest, sleep, and reverie-the brain continues to process information. In resting wakefulness, the mind generates thoughts, plans for the future, and imagines fictitious scenarios. In sleep, when the demands of sensory input are reduced, our experience turns to the thoughts and images we call "dreaming." Far from being a meaningless...

Recent studies suggest that lucid dreaming (awareness of dreaming while dreaming) might be associated with increased brain activity over frontal regions during rapid eye movement (REM) sleep. By applying transcranial direct current stimulation (tDCS), we aimed to manipulate the activation of the dorsolateral prefrontal cortex (DLPFC) during REM sleep to increase dream lucidity. Nineteen...
