 In many ancient societies, such as those of Egypt and Greece, dreaming was considered a supernatural communication or a means of divine intervention, whose message could be interpreted by people with these associated spiritual powers.In modern times, various schools of psychology and neurobiology have offered theories about the meaning and purpose of dreams.Most people currently appear to interpret dream content according to Freudian psychoanalysis in the United States, India, and South Korea, according to a study conducted in those countries.
