They shall not find lions, they shall find man himself, and the record of all his life and of his struggle with reality. Dream psychology is the key to Freud's works and to all modern psychology. With a simple, compact manual such as Dream Psychology there shall be no longer any excuse for ignorance of the most revolutionary psychological system of modern times.
