Previous questionnaire studies of parapsychological experiences have found significant interrelations between the experiences in question and dream experiences. In this study we present a replication of these relationships using a nationality of participants neglected in previous studies, a predominantly Spanish sample. A questionnaire was published in a Spanish New Age magazine. Four hundred...

This study investigated if dream content differences exist between male and female dreamers in England. One most recent dream report was collected from each of the 100 male and 100 female research participants during dream seminars and a dream research project held in England between 1990 and 2004. The Hall-Van de Castle System of Content Analysis (1966) was used to score each dream report....

Many studies have reported positive correlations between dream recall frequency (DRF) and measures of absorption, psychological boundaries and attitude towards dreams. A majority of these studies, however, have relied exclusively on retrospective measures of DRF even though daily dream logs are generally considered to be more direct and valid measures of DRF. The first goal of the present...

Dreaming reported after anesthesia remains a poorly understood phenomenon. Dreaming may be related to light anesthesia and represent near-miss awareness. However, few studies have assessed the relation between dreaming and depth of anesthesia, and their results were inconclusive. Therefore, the authors tested the hypothesis that dreaming during anesthesia is associated with light anesthesia, as...

This review summarizes the available knowledge on the phenomenology of posttraumatic dreams. Posttraumatic nightmares are reported by up to 70% of individuals suffering from posttraumatic stress disorder (PTSD). An extensive review of polysomnographic studies suggests that neither this high incidence nor the occurrence of posttraumatic nightmares throughout the sleep cycle can be explained by...

Existing sensor network architectures are based on the assumption that data will be polled. Therefore, they are not adequate for long-term battery-powered use in applications that must sense or react to events that occur at unpredictable times. In response, and motivated by a structural autonomous crack monitoring (ACM) application from civil engineering that requires bursts of high resolution...

In the 19th century, several authors held the view that nightmares are caused by oxygen shortage. The present study was designed to study nightmare frequency in patients with obstructive sleep apnea syndrome and its relationship to respiratory parameters. A brief questionnaire was administered to 323 patients with sleep apnea syndrome before their first laboratory night. The reduction in...

To study dream content in patients with severe obstructive sleep apnea syndrome (OSAS) and its modification with Continuous Positive Airway Pressure (CPAP) therapy. We assessed twenty consecutive patients with severe OSAS and 17 healthy controls. Polysomnograms were recorded at baseline in patients and controls and during the CPAP titration night, 3 months after effective treatment and 2 years...

The present study investigated frequency of dream recall in children and their mothers. Overall, 88 mothers ( M age: 38.7 yr., SD = 5.0) and their children (45 girls, 43 boys; M age: 9.9 yr., SD = 1.3) participated. A small but significant positive Pearson correlation of .19 between the frequency of dreams reported by mothers and by their children is consistent with Cohen's 1973 hypothesis of a...

The dual rhythm model of dreaming states that, under high sensory thresholds, heightened general cortical activation common to both REM/NREM and circadian-driven activation cycles sums to produce the main characteristics of dreaming. In addition, the unique pattern of regional brain activation characteristic of REM sleep amplifies the emotional intensity of the dream. Subjects were awakened...
