Jung contrasted the collective unconscious with the personal unconscious, the unique aspects of an individual study which Jung says constitute the focus of Sigmund Freud and Alfred Adler. Psychotherapy patients, it seemed to Jung, often described fantasies and dreams which repeated elements from ancient mythology. These elements appeared even in patients who were probably not exposed to the original story. For example, mythology offers many examples of the "dual mother" narrative, according to which a child has a biological mother and a divine mother. Therefore, argues Jung, Freudian psychoanalysis would neglect important sources for unconscious ideas, in the case of a patient with neurosis around a dual-mother image.
