The Interpretation of Dreams by Sigmund Freud, the founder of psychoanalysis, is a significant work in which Freud introduces his theory of the unconscious regarding dream interpretation, and explores what would later become known as the Oedipus complex. Freud argued that dreams are products of both unconscious forces and censorship that forcibly distorts the expression of the wish. The book also examines dream symbolism, dream content, and sources of dream content. Despite criticisms that Freud's dream theory requires sexual interpretation, Freud insists that the interpretation of dreams is the key to understanding the unconscious activities of the mind.
