Toilet dreams: Incorporation of waking-life memories?
Toilet dreams are quite common but have been very rarely studied systematically. Many authors assume that the urge to urinate is the basic trigger for these dreams. Analyzing the frequency and characteristics of toilet dreams in a long dream series supports the idea that these dream topics are related to waking-life memories – especially waking-life thoughts. It would be very interesting to study whether intraindividual night-to-night fluctuations regarding the urge to urinate and/or interindividual differences are related to the frequency of toilet dreams.
