The current study examined the effects of Meditation and Sleep Mentation Therapy on mood levels. All participants were male, and currently in treatment programs or early stages of recovery from alcohol and drug addiction. Participants were tested for anxiety and depression symptoms and were asked to provide a recent dream, prior and post to participating in the intervention. Dreams were scored using Hall and Van de Castle guidelines for scoring imagery. Results are consistent with previous research in that mood levels changed over the course of the meditation period. Implications for future research are discussed as well as applications of Sleep Mentation Therapy and Meditation in clinical and applied practice.
