Oneiromancy

Oneiromancy (from the Greek όνειροϛ oneiros, dream, and μαντεία manteia, prophecy) is a form of divination based upon dreams; it is a system of dream interpretation that uses dreams to predict the future. The Swiss psychotherapist and psychiatrist who developed the field of analytical psychology, Carl Gustav Jung, focused this idea and formed theories, experiments, and terminology around oneiromancy.
