Abstract
Mystical dynamics-the notion that mystical oneness may unfold involving ego disintegration, renewal, and luminous light-has been discussed anecdotally by psychedelic researchers and therapists but has not yet been empirically examined in controlled settings. This study investigated the occurrence and dose-dependency of mystical dynamics in healthy participants after administration of psychedelics. A total of 816 mystical-dynamics measurements were collected from 386 participants across 15 studies at two sites: University Hospital Basel (Switzerland) and Johns Hopkins University (USA). Participants received low to high doses of four serotonergic psychedelics: LSD, psilocybin, mescaline, and DMT. Mystical dynamics was assessed using five corresponding constructs from the Psychedelic Experience Scale (PES100): ego disintegration, distress, renewal, luminous light, and mystical (focusing on mystical oneness, the core of mystical experience). We hypothesized strong intercorrelations of mystical oneness with ego disintegration, renewal, and luminous light, and a dose-dependent intensity pattern. Results showed dose-sensitive strong correlations of mystical oneness with luminous light and renewal, and a moderate-to-strong correlation of mystical oneness with ego disintegration. These findings support a broader, dynamic model of mystical experience and offer novel insights relevant to psychedelic-assisted therapy, while acknowledging additional experiential features that may also associate with mystical oneness.
