- Dream recall frequencies and dream content in Wilson’s disease with and without REM sleep behaviour disorder: A neurooneirologic studyPublication . Tribl, Gotthard G.; Trindade, Mateus C.; Schredl, Michael; Pires, Joana; Reinhard, Iris; Bittencourt, Thais; Lorenzi-Filho, Geraldo; Alves, Rosana Cardoso; Andrade, Daniel Ciampi de; Fonoff, Erich T.; Bor-Seng-Shu, Edson; Machado, Alexandre A.; Teixeira, Manoel J.; Barbosa, EgbertoObjective. 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 prospective two-week home dream diary with self-rating of emotions and blinded, categorical rating of contentby an external judge. Results. WD patients showed a significantly lower dream word count and very few other differences in dream characteristics compared to age- and sex-matched healthy controls. Compared to WD patients without RBD, patients with WD and RBD reported significantly higher nightmare frequencies and more dreams with violent or aggressive content retrospectively; theirprospectively collected dream reports contained significantly more negative emotions and aggression. Conclusions. The reduction indream length might reflect specific cognitive deficits in WD. The lack of differences regarding dream content might be explained bythe established successful WD treatment. RBD in WD had a strong impact on dreaming. In accordance with the current definitionof RBD, violent, aggressive dream content seems to be a characteristic of RBD also in WD.
- Dream reflecting cultural contexts: comparing Brazilian and German diary dreams and most recent dreamsPublication . Gotthard, Tribl; Beuerle, Franziska; Trindade, Mateus C.; Lorenzi-Filho, Geraldo; Pires, Joana; Barbosa, Egberto; Schredl, MichaelThe continuity hypothesis states that waking life experiences, e.g., personal concerns and cultural environment, are refl ected in dreams. The present study’s goal was to compare written dream reports from Brazilian and German samples. Overall, 97 Brazilian participants were included; two German samples from previous studies (N=89 and N=4197) were selected for comparison. The Brazilian participants reported 328 and the German participants 348 diary dreams. In addition, 86 Brazilian to 2893 German most recent dreams were compared. For both types of collected dreams, we found more bizarreness in German reports, and more depression-related topics in Brazilian reports. Germans reported more aggression in diary dreams and both more problems and more extreme emotions in most recent dreams. Brazilians reported more work- and leisure-related topics in diary dreams. Several similarities in dream content, e.g., no differences in verbal and physical interaction, number of male and female characters, and death-related themes, hint at universal characteristics of dreaming across cultures. We consider the clear group differences in dream content to refl ect basic patterns of Brazilian and German cultures, which is exemplifi ed through some core topics of the respective cultural sets. Concerning Brazil, the themes of miscegenation, emotional culture, and “saudade” (“longing”) are discussed. For German culture, the area of confl ict between long-standing high-performance in science and arts and the contrasting twentieth century history is addressed. Future research should study the relation between dream content and culture in representative samples; to this purpose dream diaries, sampling daily average dreams, seem preferable to most recent dreams.
