“…Breger, 1967;Koulack, 1993;Piccioni et al, 2002;Wright & Koulack, 1987). For example, dreams are very clearly affected by traumatic experiences (see reviews by, for example, Barrett (1996) and Punamäki (2007)), and other more common stressful waking-life experiences such as surgery (Breger, Hunter, & Lane, 1971) and divorce (Cartwright, 1991(Cartwright, , 2011Cartwright et al, 1984;Cartwright et al, 2001;Cartwright et al, 2006). However, while some experimental studies have found measurable effects of stressful experiences on dreams, mostly in terms of dream affect (de Koninck & Brunette, 1991;de Koninck & Koulack, 1975;Koulack et al, 1985), a naturalistic study found no effect either in terms of direct or indirect incorporations, or changes to dream affect (Delorme et al, 2002).…”
