Sherwood, S. J. and Roe, C. A. (2013) An updated review of dream ESP studies conducted since the Maimonides Dream ESP Program. In: Krippner, S., Rock, A. J., Beischel, J., Friedman, H. L. and Fracasso, C. L. (eds.) Advances in Parapsychological Research 9. Jefferson, NC: McFarland. pp. 38-81.
We review the dream ESP studies conducted since the end of the Maimonides research programme. Combined effect size estimates for both sets of studies (Maimonides r = 0.33, 95% C.I. 0.24 to 0.43; post-Maimonides r = 0.14, 95% C.I. 0.06 to 0.22) suggest that judges could correctly identify target materials, more often than would be expected by chance, using dream mentation. Maimonides studies were significantly more successful (p< 0.05) than post-Maimonides studies, which may be due to procedural differences, including that post-Maimonides receivers tended to sleep at home and were generally not deliberately awakened from REM sleep. Methodological shortcomings of some studies are discussed. Nevertheless, home dream ESP research has been successful and continues to be a less expensive and less labour-intensive alternative to sleep-laboratory-based research. We hope that interest in dream ESP research will be re-awakened.
