Several studies have found an association between frequency of dream recall and creativity. We tested the hypothesis that training individuals to increase dream recall by means of a daily dream log would increase scores on the Torrance Test of Creative Thinking (TTCT). One hundred twenty‐five participants completed a baseline measure of creativity (TTCT, figural version) as well as of dream recall, dissociation, thinness of psychological boundaries, mindful‐attention awareness, and well‐being. Participants were randomly allocated to two groups: the experimental group (n = 55) received a daily dream log; while the control group (n = 32) received a similarly phrased log registering memories of a vivid episode from the previous day. After 27 days, all participants completed follow‐up measurements identical to those at baseline. A non‐randomized non‐intervention group (n = 35) was used to test for practice effects on the TTCT. There was significant selective increase for the “creative strengths” component, which was only observed in the experimental group. There were significant correlations between creativity and dissociation as well as between creativity and thinness of psychological boundaries. Enhanced dream recall through daily dream logging fosters aspects of creativity. Associations between creativity, dissociation, and thinness of boundaries, suggest that increased awareness to dreams increases creativity through a “loosening” of stereotyped thinking pattern.
