Among 227 naturalistic DMT experiences that felt familiar, the familiarity was not attributed to a prior psychedelic experience. Most (97.4%) included features of a mystical experience, 16.3% involved ego-dissolution, and 11.0% a profound sense of death. A new questionnaire identified five themes of familiarity: feeling or knowledge gained; place or environment; the act of going through the experience; transcendent features; and familiarity imparted by an entity encounter. Two stable participant classes emerged: one class more often reported familiarity from an entity encounter and from the feeling or knowledge gained. The sense of familiarity during DMT appears non-referential to past psychedelic use.
