ZusammenfassungPrevious research has shown that external stimuli were often incorporated into the dream to some extend. The aim of the present study was to investigate whether the internal stimulus sleep apnea is also incorporated into dreams. Findings showed, however, that direct incorporation occurs very seldom. On the other hand, arousals accompanying sleep apneas seem to interfere with dream formation since a marked reduction of dream bizarreness is related to high RDI (respiratory disturbance index). Additionally, small indirect effects on dream content by day-time stressors such as cognitive deficits and sleepiness are suggested by the data. A heightened dream recall frequency in patients with sleep apnea was found. Future dream research should focus on studies including sophisticated EEG analysis methods and detailed measures of day-time symptoms present in patients with sleep apnea.Keywords dream recall -internal stimuli -respiratory disturbance index.Die bisherige Forschung zeigte, dab externe Stimuli teilweise Eingang in den Traum finden. Das Ziel der vorliegenden Studie war die Untersuchung, ob dies in ~ihnlicher Weise auf ftir einen internen Stimulus wie die Apnoephase gilt. Die Ergebnisse zeigen jedoch, dab ein direkter Einflug auf den Trauminhalt sehr selten vorkommt. Auf der anderen Seite zeigte sich, dab die Weckreaktionen, die mit den Apnoephasen einher gehen, mit dem Traumbil-dungsprozeB interferieren, da eine deutliche Reduktion der Traumbizarrheit mit einem hohen RDI (Respiratory Disturbance Index) korreliert. Eine erh6hte Traumerinnerung wurde ftir die Schlaf-Apnoe-PatientInnen gefunden. Zuktinftige Forschung sollte sich auf Studien konzentrieren, die ausgekltigelte EEG-Analysemethoden und genauere Mage ftir das Vorkommen von Stressoren im Wachteben von Schlaf-Apnoe-PatientInnen beinhalten.SchliisselwOrter Traumerinnerung -interne Stimuli -RDI.<
