Personality regression can be described as a mental state in which one suddenly adopts an identical personality, set of mannerisms and behaviors to that of their past self from a younger age. This is often capable of making one believe that they are a child again and begin acting appropriately to this belief. There are also anecdotal reports of people speaking in languages which they have not used for many years under the influence of this effect.
Personality regression is a very rare and uncommon effect which can spontaneously accompany high level memory suppression and ego death. It is most commonly induced under the influence of heavy dosages of hallucinogenic compounds such as psychedelics, dissociatives, and deliriants.
Compounds which may cause this effect commonly include:
1P-LSD, 4-AcO-DMT, ALD-52, Ayahuasca, LSD, Psilocin, Psilocybin mushroom
