Rumination and mindfulness are transdiagnostic risk and protective factors while their role in Premenstrual Dysphoric Disorder (PMDD) is unclear. Thus, we aimed to investigate the cycle-phase-specific effects of rumination and mindful self-focus on momentary mood and cognitions in women with and without PMDD. This study involved brief ambulatory inductions of ruminative and mindful self-focus...
Individuals who frequently experience nightmares report compromised sleep quality, poor daytime mood, and functioning. Previous research has aimed at linking these impairments with altered sleep architecture, but results were inconclusive. One plausible explanation is that only a few studies recorded markers of autonomic nervous system activity. For the first time, this study collected such...
Objective. Violent dream content and its acting out during rapid eye movement sleep are considered distinctive for rapid eye movement sleep behaviour disorder (RBD). This study reports first quantitative data on dreaming in a cohort of patients with treated Wilson's disease (WD) and in patients with WD with RBD. Methods. Retrospective questionnaires on different dimensions of dreaming and a...
The experience of post-amputation pain such as phantom limb pain (PLP) and residual limb pain (RLP), is a common consequence of limb amputation, and its presence has negative effects on a person's well-being. The continuity hypothesis of dreams suggests that the presence of such aversive experiences in the waking state should be reflected in dream content, with the recalled body representation...
The percentages of successful dream recall vary depending on whether the participants were awakened from REM sleep (about 80% recall) or NREM sleep (about 50% recall). The question as to whether this difference is explained by less dreaming during NREM sleep or sleep state-dependent memory processes cannot answered easily. The present pilot study was designed to test whether high recallers can...
Many studies have reported gender differences in nightmare frequency. In order to study this difference systematically, data from 111 independent studies have been included in the meta-analysis reported here. Overall, estimated effect sizes regarding the gender difference in nightmare frequency differed significantly from zero in three age groups of healthy persons (adolescents, young adults,...
Emotions are an integral part of dreaming. From the viewpoint of the continuity hypothesis, two areas are of interest: how are dream emotions affected by day-time mood and how do dream emotions affect subsequent waking life. Seventy-four participants kept a diary over a 2-week period recording daytime mood, emotional valence of daytime events, and their dreams. Confirming earlier findings, the...
SummaryMany studies have reported gender differences in dream recall. Data from 175 independent studies have been included in the analyses. Overall, estimated effect sizes in five age groups of healthy persons differed significantly from zero. Variables like measurement method and publication year did not affect the gender difference but age groups showed different effect sizes. The smallest...
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...
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.
