Ego replacement

Ego replacement is defined as the sudden perception that one's sense of self and personality has been replaced with that of another person's, a fictional character's, an animal's, or an inanimate object's perspective. This can manifest in a number of ways which include but are not limited to feeling is one has literally become another human, animal, or alien consciousness. During this state, the person will be unlikely to realize that their personality has been temporarily swapped with another's and will usually not remember their previous life.

Ego replacement is often accompanied by other coinciding effects such as delusions, psychosis, and memory suppression. It is most commonly induced under the influence of moderate dosages of heavy dosages of hallucinogenic compounds, such as psychedelics, dissociatives, and deliriants.
