C.G. Jung: The Principle of Understanding Dreams Symbolically
It is a well-known fact that one of the principles of analytic psychology is that the dream images are to be understood symbolically; that is to say, that they are not to be taken literally just as they are presented in sleep, but that behind them a hidden meaning has to be surmised.
It is this ancient idea of a dream symbolism which has challenged not only criticism, but, in addition to that, the strongest opposition. That dreams may be full of Import, and, therefore, something to be interpreted, is certainly neither a strange nor an extraordinary idea this has been familiar to mankind for thousands of years, and, therefore, seems much like a banal truth the dream Interpretations of the Egyptians and Chaldeans, and the story of Joseph who interpreted Pharaoh’s dreams, are known to everyone, and the dream book of Artemidorus is also familiar.
From countless inscribed monuments of all times and peoples we learn of foreboding dreams, of significant, of prophetic and also of curative dreams which the Deity sent to the sick, sleeping in the temple.
