Such dreams are called by primitives ‘big’ dreams. The primitives I observed in East Africa took it for granted that ‘big’ dreams are dreamed only by ‘big’ men—medicine-men, magicians, chiefs, etc.
Jung provides the ethnographic origin and psychological rationale for the term, identifying big dreams as mythologically structured, collective in scope, and requiring specialized interpretive knowledge.
