And how about the value of the dream for a knowledge of the future?  That, of course, we cannot consider.  One feels inclined to substitute:  “for a knowledge of the past.”  For the dream originates from the past in every sense.  To be sure the ancient belief that the dream reveals the future is not entirely devoid of truth.  By representing to us a wish as fulfilled the dream certainly leads us into the future; but this future, taken by the dreamer as present, has been formed into the likeness of that past by the indestructible wish.
