Sigmund Freud 
The Interpretation of Dreams (Annotated) 

The Interpretation of Dreams (German: Die Traumdeutung) is a book by psychoanalyst Sigmund Freud. The book introduces Freud’s theory of the unconscious with respect to dream interpretation, and also first discusses what would later become the theory of the Oedipus complex. His ground breaking theories of the id, ego, and super-ego of the mind continue to be studied throughout the world.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. Freud said of this work, ‘Insight such as this falls to one’s lot but once in a lifetime.’The work gained popularity as Freud did, and seven more editions were printed in his lifetime.The text was translated by A. A. Brill, an American Freudian psychoanalyst, and later in an authorized translation by James Strachey, who was British. Because the book is very long and complex, Freud wrote an abridged version called On Dreams.
