Die Traumdeutung, which translates as 'The Interpretation of Dreams', is one of the seminal works of psychoanalysis literature. Written by Sigmund Freud, it introduces his theory of the unconscious with respect to dream interpretation and also discusses what would later become the theory of the Oedipus complex. Freud revised the book at least eight times and, in the third edition, added an extensive section which treated dream symbolism very literally, following the influence of Wilhelm Stekel.
