The myth is the public domain and the dream is the private myth. If your private myth, your dream, happens to coincide with that of the society, you are in good accord with your group. If it isn't, you've got a long adventure in the dark forest ahead of you.
Joseph CampbellDream is personalized myth, myth is depersonalized dream; both myth and dream are symbolic in the same general way of the dynamics of the psyche. But in the dream the forms are quirked by the peculiar troubles of the dreamer, whereas in myth the problem and solutions shown are directly valid for all mankind.
Joseph Campbell
