In the early years of the 20th century, Carl Jung (at one time Sigmund Freud's favorite pupil) developed his own system of depth psychology. He was particularly interested in dream analysis and the light they threw upon what was happening in the subconscious levels of his patients' minds.

In this program, we explore his fascinating discoveries. Featuring renowned author and researcher Adrian Gilbert, in this ongoing series of occult and esoteric knowledge.
