That's one of the signatures of a psychedelic experience. There's plenty of research on the subject, this study came up on a quick Google search. https://pubs.acs.org/doi/10.1021/acsptsci.0c00194 https://pubs.acs.org/doi/10.1021/acsptsci.0c00194 > Our position contrasts the idea that subjective effects of psychedelics may be irrelevant to their therapeutic effects. > The meaning and significance attributed to psychedelic experiences has been well established in laboratory settings. Psilocybin administration studies have repeatedly shown that participants frequently rate their psychedelic experiences as among the most meaningful of their entire lives (5,6,8,16−19) and they are sometimes compared to the birth of a first-born child or death of a parent. Due to their salience, such experiences may serve as narrative “inflection points” in one’s life that could provide an impetus for changing one’s identification with certain patterns of thoughts, feelings, and behaviors.
