Psychoanalysis is a set of theories and therapeutic techniques related to the study of the unconscious mind, which together form a method of treatment for mental disorders.The primary assumption of psychoanalysis is the belief that all people possess unconscious thoughts, feelings, desires, and memories.The aim of psychoanalysis therapy is to release repressed emotions and experiences, i.e., make the unconscious conscious. It is only having a cathartic (i.e., healing) experience can the person be helped and "cured."
