Psychoanalysis is a psychological theory developed by Sigmund Freud involving unconscious mental processes, resistance and repression, and the importance of sexuality. Freud believed the mind is divided into the conscious mind, which we are aware of, and the unconscious mind, containing unacceptable thoughts and influences on our behavior outside of our awareness. Jung disagreed with Freud's emphasis on sexuality and proposed concepts like the archetype, collective unconscious, and complex, which are patterns of emotion and perception that help form characters and relate to audiences.
