Unconcious Mind

In the early 1900s, the Austrian neurologist Sigmund Freud established a revolutionary theory called psychoanalysis, related to the study of the unconscious mind. As his work took hold, a number of followers were invited to meet at Freud's apartment every Wednesday afternoon to discuss various ideas about psychology and the meanings of dreams. This group was called the Wednesday Psychological Society. It marked the beginning of the worldwide psychoanalytic movement.
