Experienced lucid dreamers who used the supplement galantamine to induce dreams reported that it significantly increased dream length and vividness while decreasing negative aspects such as fear, violence, and threatening characters, based on retrospective questionnaire responses from 18 participants.
A pre-sleep protocol combining the drug galantamine with middle-of-the-night meditation and imaginary reliving of a distressing dream while practicing new responses increased lucidity and constructive actions in dreams. Thirty-five participants completed eight nights comparing six conditions, including Wake-Back-to-Bed alone, with placebo, or with galantamine, and meditation and dream reliving alone, with placebo, or with galantamine. Self-ratings showed that the protocol enhanced reflectiveness, interactive behavior, role change, and reduced fear and threat. The findings support further study of this approach for lucid dream induction and nightmare or trauma resolution.
