“…In representative studies ( Schredl, 2008 , 2009 ), the mean dream recall is once per week. A wide variety of factors affect intra-individual fluctuations, and inter-individual differences in dream recall, for example, sleep duration ( Schredl & Fulda, 2005 ), nocturnal awakenings ( Schredl et al, 1998 ), default mode network connectivity ( Vallat et al, 2022 ), personality dimensions such as absorption ( Beaulieu-Prevost & Zadra, 2007 ), boundary thinness ( Hartmann, 1989 ), and openness to experience ( Schredl & Göritz, 2017 ). Even though comprehensive models of dream recall have been proposed ( Schredl, 2018 ), Schonbar (1965) has put forward a very specific theoretical framework, the so-called “life-style hypothesis of dream recall”, to explain stable inter-individual differences in dream recall frequency, that is, persons with high introspection, who are interested in psychological topics, vivid imagination tend to recall dreams more often.…”
