He also considered the ideas and actions of human beings to be the expression of instincts (Approaches to Greek Myth, 1990, p. 422). Freud suggests that people have strong desires that are taboo and society prevents them from expressing them. Therefore, myths are the psyche's symbolic representation of its own functioning and can be translated by the analyst. He introduces his theory of the “Unconscious Mind”, better known as Id, Ego and Superego. This theory explains that people's unconscious desires take control of their actions. The id is the instinctive component of the personality, it responds directly and immediately to instincts. The Ego is the realistic principle; is concerned with devising a realistic way to obtain pleasure. The superego helps control the impulses of the id and is made up of the conscience and the ideal self. According to Freud, children are born with only the id, which makes them act only on impulse. He connects it to dreams and states that people's dreams are outlets for our repressed desires. Many of these interpretations can be supported by evidence from poems, such as Oedipus. Freud's psychoanalysis focuses on the story as a whole, so Freud is actually analyzing the person who wrote the myth and the behavior of society at that time.
