The central goal of Freudian psychoanalysis is to make the patient aware of what is hidden in his/her unconscious.
ID: Primal urges, food, sex, aggression. The ID "drives" instinct. Entirely subconscious
EGO: Mediator between primal urges and behavior accepted in reality
SUPEREGO: Moral values, conscience; can lead to self-blame and attacks on ego.
