This book is the second volume of the ten-volume collected works of the Austrian scientist and psychologist, the founder of psychoanalysis, Sigmund Freud, known as the Study Edition. “The Interpretation of Dreams” gives the reader the key to the entire psychoanalytic concept: it clarifies the main concepts, terms, images, and reveals the rich symbolism of dreams. Freud explains and investigates in detail the mechanisms and laws by which dreams are “built,” and the reader can move step by step along the “royal road” to the unconscious together with the author.
