From Dr. Eisenbud's book we learn:

Among the neurotic affectations manifested by Serios are: the claim that the presence of metal on himself interferes with his psychic power; complaint of frequent severe headaches; complaint of bleeding from the mouth and anus after concentration; habituation of the rolled piece of paper called a gismo,which he uses during photography sessions. (He says he is uncomfortable without it.)

He is a compulsive liar and often lies for no obvious reason. He also seems to have paranoid tendencies and has threatened to seek revenge against at least one person who, he thinks, believes he is a fraud.

He feels that he has not been recognized for his power and that he should be honored with awards.

He is masochistic, often picking fights with men who are obviously physically stronger than he. He invites trouble in bars and is often badly beaten.

He has little respect for women and prefers his sex partners "dirty and dumb." He seems to be anxious to exhibit himself naked to strangers (men) and has done this more than once.
