Secondly, these symbolic representations are peculiar neither to the dreamer nor to the dream work by means of which they become expressed. We have learned that mythology and fairy-tales make use of the same symbolism, as well as do the people in their sayings and songs, the ordinary language of every day, and poetic phantasy. The field of symbolism is an extraordinarily large one, and dream symbolism is but a small part thereof. It is not even expedient to approach the whole problem from the dream side. Many of the symbols that are used in other places do not occur in the dream at all, or at best only very seldom. Many of the dream symbols are to be found in other fields only very rarely, as you have seen. One gets the impression that he is here confronted with an ancient but no longer existent method of expression, of which various phases, however, continue in different fields, one here, one there, a third, perhaps in a slightly altered form, in several fields. I am reminded of the phantasy of an interesting mental defective, who had imagined a fundamental language, of which all these symbolic representations were the remains. Thirdly, you must have noticed that symbolism in these other fields is by no means sex symbolism solely, while in the dream the symbols are used almost entirely to express sexual objects and processes. Nor is this easily explained. Is it possible that symbols originally sexual in their meaning later came to have other uses, and that this was the reason perhaps for the weakening of the symbolic representation to one of another nature? These questions are admittedly unanswerable if one has dealt only with dream-symbolism. One can only adhere to the supposition that there is an especially intimate connection between true symbols and things sexual.
