The superego is a concept of the structural model of psychology and the three-instance model of Sigmund Freud. According to this, the personality is divided into three instances: Superego, Ego and Id. The superego represents the psychic instance, the values and norms. It is shaped by social values and norms and one's own sense of morality, which develops in early childhood. It thus represents the forbidding and commanding instance of conscience. Sigmund Freud himself was involved with hypnosis at the beginning of his work. Hypnosis may have influenced him in his exploration of the three-instance model. The core idea that different levels of consciousness exist and that one uses the unconscious for healing is also used in hypnotherapy.
