What is Personation?
Personation— The temporary assumption of another's physical characteristics, habits, symptoms of illness or other identifying traits, personation is frequently experienced by participants in seances, with the individuals personated usually being known to them. Mediums often experience personation of subjects not known to them but known to their clients. In one unusual case of hysterical personation a young woman rejected by a lover began to display many of the young man's gestures, to speak in a voice resembling his and to change her hand-writing to approximate his. In addition, personation is rather easily achieved in the hypnotic state by suggestion.
