The catalysis of psychotherapeutic processes by psychedelics – Psychedelic-assisted psychotherapy (PAP) combines psychedelic substances with psychotherapeutic techniques to achieve rapid and profound changes. The oceanic feeling seems to play a crucial role in the action of these substances. PAP reinforces several universal factors in psychotherapy, including the therapeutic relationship, motivational clarification, actualization of problems, resource activation, and problem-solving. In particular, the deeper insights gained during the experience support motivational clarification and creative problem-solving approaches.
