An out-of-body experience (OBE) can be defined as having the impression of being consciously aware and out of one's physical body in an extrapersonal location. Recent research has suggested that OBEs are often a response to physical and/or psychological threat. However, because the OBE does not occur for everyone even when in the same type of threatening situation, it has been further...
Body-mind-based holistic methods of relaxation and improved well-being, such as yoga and meditation, improve body awareness and have often been used to enhance quality of life and the ability to cope with pain. We aimed to compare tactile sensory acuity and body awareness in healthy sedentary individuals who practiced yoga regularly and in control participants who had not practiced yoga....
Mindfulness-acceptance commitment interventions in sport and exercise contexts have been helpful to increasing a positive psycho-physiological state among competitive athletes and recreational exercise participants. In the current study, we sought to extend research in this area by identifying the effect of a brief-mindfulness intervention on psychophysiological functioning among healthy but...
It is becoming clear that to truly understand what it is to be human, focusing scientific efforts on the mind alone is insufficient. We are embodied minds, living and acting in a world full of meaningful things. In this article, we discuss how science has been informed by important research insights into the close relationship between the body, the mind, and the world. These interactions can be...
Anecdotal evidence indicates that supplementation with vitamin B6 (pyridoxine) before bed can enhance dream vividness and recall. In a single pilot study, Ebben, Lequerica, and Spielman (2002) found that vitamin B6 had a dose-dependent effect of increasing scores on a composite measure of dream vividness, bizarreness, emotionality, and color. The present research replicated this study using a...

The present study addressed whether a spatial matching task relying on inter-sensory judgments might be influenced by the transition between egocentric and decentered mode of thinking. Thirty-six children aged 5, 7, or 9 years performed a paramedian correspondence task with conditions requiring inter-sensory integration (visual-proprioceptive) and a problem-solving task. The visual information...
Prior research has shown that methods of meditation, breath control, and different kinds of yoga breathing affect attention and visual perception, including decreasing the size of certain optical illusions. Evaluating relationships sheds light on the perceptual and cognitive changes induced by yoga and related methods, and the locus of the effects. In the present study, the degree of optical...
Lucid dreams occur when a person is aware that he is dreaming while he is dreaming. In a representative sample of German adults (N = 919), 51% of the participants reported that they had experienced a lucid dream at least once. Lucid dream recall was significantly higher in women and negatively correlated with age. However, these effects might be explained by the frequency of dream recall, as...
Some of the most popular meditation practices emphasize a relaxed focus of attention in which thoughts, images, sensations, and emotions may emerge and pass freely without actively controlling or pursuing them. Several recent studies show that meditation activates frontal brain areas associated with attention focusing and physical relaxation. The objective of the present study was to assess...
The effects of sociodemographic variables on dream recall frequencies were investigated in a representative sample. Analysis indicated that age, sex, social class, and the size of the place of residence showed small but significant effects on the frequency of positively toned and neutral dreams. Women and inhabitants of large cities tended to report dreams more often than men and residents of...
The present study investigated the effects of sociodemographic variables on dream recall frequencies in a representative sample of 931 persons over 14 years of age. Analyses indicated that age, sex, and the size of the place of residence had small but significant effects: women and inhabitants of large cities tend to report dreams more often than men and residents of small towns. There was also...
Longer sleep duration should be related to dream recall (longer REM sleep), but previous findings regarding the relationship between habitual sleep duration and dream recall frequency have been conflicting, whereas experimental manipulation of sleep duration yielded a significant effect. The analysis of diaries kept by the 444 participants over 14 days indicated that intra-individual...
Whereas the effect of sex and age on dream recall have been studied widely, socioeconomic status has rarely been investigated. However, two studies reported that higher socioeconomic status was related to greater frequency of dream recall. In the present sample of 612 Chinese students from three different schools, one elite (high socioeconomic status), one rural (low socioeconomic status) and...
Research with animals and humans has suggested that acute and subacute use of 3,4-methylenedioxymethamphetamine (MDMA “ecstasy”) may lead to memory impairment. However, research is limited by (1) low power due to small sample sizes, (2) the possible confound of polydrug use, and (3) the failure to consider intelligence as a covariate. The present study compared the memory performance on the...
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...
A conceptual replication of the link between self-reported dissociative alterations in body-image under experimental conditions and the reporting of prior out-of-body experiences in a recent data set was undertaken. Also examined was whether this relationship would hold for experiences reported during the experimental context and whether it is independent of self-reported New Age belief. Data...
The present study investigated dream recall as well as nightmare frequency in families. Whereas a positive correlation for nightmare frequencies between children and mothers was found (but not for children and their fathers), the relationship for dream recall frequency was small and nonsignificant. Assuming that mothers are still the primary caregivers in the modern family, and, thus, might...
There is ongoing debate on whether the full moon is associated with sleep and dreaming. The analysis of diaries kept by the participants ( N = 196) over 28 to 111 nights showed no association of a full moon and dream recall. Psychological factors might explain why some persons associate a full moon with increased dream recall.
Previous research regarding the relationship between habitual sleep duration and frequency of dream recall yielded conflicting results, whereas experimental manipulation of sleep duration showed a significant effect on dream recall. In this study analyzing both effects simultaneously, the findings from diaries kept by the 196 participants over 28 to 111 days indicated that intra-individual...
This work evaluated the association of age and dream reports. The verbal reports of 148 dreams of elderly people (M age=75.8 yr.) were compared with 151 dreams of a group of young people (M age=22.0). The dreams were analyzed according to the Jungian vision (which looks at the dream as a text produced by the dreamer's unconscious while sleeping), using processing techniques derived from textual...
In a sample of 71 medical students, dream recall frequency was positively correlated with proneness to altered states of consciousness ( r = .26) measured by the State of Mind and Consciousness Questionnaire and dissociation ( r = .29) measured by the Dissociative Experiences Scale II. A regression analysis, however, yielded neither altered states of consciousness nor dissociation, sex, or age...
A 23-yr.-old young woman presenting with a 17-yr. history of nightmares was treated with a variety of behavioral and self-regulatory techniques. The nightmares were unusual in that they did not have an obviously common theme as in most published reports, and, therefore, did not readily lend themselves to several frequently used techniques. Although previous treatment episodes had not affected...
