The continuity hypothesis of dreaming states that dreams reflect waking life, however, research has also shown that dreams can affect waking life, e.g., creativity, daytime mood. So far, factors that are associated with the effect of dreams on waking life have been rarely studied. Overall, 2492 persons (1437 woman, 1055 men) with a mean age of 47.75 ± 14.41 years participated in the study. The...
The basic definition of lucid dreaming is that the dreamer knows that s/he is dreaming while still dreaming. However, the skills within the lucid dream, e.g., regarding dream control, vary considerably from dreamer to dreamer. The present study tested the psychometric properties of the Lucid Dreaming Skills Questionnaire (LUSK) in a sample of 1267 persons. The findings indicate that the LUSK...
Chronotype refers to individual differences in sleep timing ("owls" and "larks") and "eveningness" has been associated with nightmares. However, it has not been tested as to whether neuroticism mediates this relationship. Urbanicity refers to being raised in an urban region and/or currently living in an urban region and is associated with heightened risk for developing mental disorders, and...
Models of nightmare aetiology postulate an interaction between trait and state factors. However, most of the studies that support these models have been cross-sectional and longitudinal studies are scarce. The present data were obtained from N = 888 participants completing two online dream studies carried out independently with the same online panel 2 years apart. Nightmare frequency declined...
A fascinating area of dream research is the analysis of long dream series. However, research regarding differences between long-term journalists and normal persons is lacking. The present online survey (N = 2,492) focused on the relationship between the Big Five personality dimensions and frequency of recording dreams. As expected, dream recall frequency, nightmare frequency, and attitude...
A variety of induction techniques have been proposed to increase lucid dream frequency. An online survey was performed asking about knowledge of lucid dreaming and lucid dream induction techniques. The initial sample size was N=1380 with a subsample of N=716 who were asked questions concerning lucid dream induction techniques. The findings indicate that one quarter of all participants had heard...
Lucid dreams are dreams that involve awareness of dreaming while dreaming. As lucid dreaming is accompanied by heightened cortical activation, e.g., in the prefrontal cortex, it was speculated whether lucid dreaming interferes with the restorative function of sleep. Two cross-sectional studies have found inhomogeneous results regarding the relationship between lucid dream frequency and...
Even though the common diagnostic criteria (ICSD-3, DSM-5) acknowledge that nightmares do not only contain anxiety/fear (definition of the ICD-10) but also other emotions such as grief, disgust, and anger, the definition of a nightmare still focuses on threats to survival, security, or physical integrity. However, empirical studies on nightmare content in larger samples are scarce. The current...
Chronotype refers to individual differences in sleep timing and in preferences for a given time of day while sleep duration refers to the hours of sleep. Here, we assessed chronotype, sleep duration, and nightmare frequency in relation to the Big Five personality factors. Overall, 2,492 persons (1,437 women, 1,055 men) completed the online survey between March 23, 2015, and April 8, 2015. The...
Visual elements are important ingredients of dreams, so dream objects should be – based on the continuity hypothesis of dreaming – as colorful as the waking world. However, the percentages of recalled colored versus black and white dreams as estimated by the participants varied considerably across studies. In the present online study, 2701 persons completed a question about recalling colors in...
There have been many recent studies that proofed the continuity hypothesis which suggests that dream content reflects waking life experiences. This study investigated factors that affect the frequency of sport and politics dreams. The online survey (N=2929 German speaking participants) showed a prevalence of about 6% sport dreams and 4% politics dreams. Results indicated that younger and male...
Despite numerous anecdotal accounts of music dreams, empirical research in this area is scarce. The present online study (N = 2929) found a prevalence of about 6% of all dreams include some element of music. Age was negatively related to the frequency of music dreams, whereas dream recall frequency, the overall emotional tone of the dreams, and the attitude towards dreams showed positive...
The present study elicited a variety of coping strategies for nightmares in the general population and asked whether these coping strategies were helpful. A large-scale online survey (N=2 872, mean age: 43 years) was carried out. About 11.5% of the participants reported nightmares once a week or more often. The results indicate that sharing of nightmares was the most prevalent coping strategy,...
Despite the large number of studies addressing gender differences in dream recall and dream content, research regarding whether these differences might be affected by sex role orientation is rather scarce. The present online-survey included a large sample of most recent dreams. The results clearly indicate that sex role orientation (femininity/expressivity and masculinity/instrumentality)...
