问答题

All other previous attempts to solve the problems of dreams have concerned themselves directly with the obvious dream-content as it is retained in the memory. They have sought to obtain an interpretation of the dream from this content, or, if they did without an interpretation, to base their, conclusions concerning the dream on the evidence provided by this content. We, however, are confronted by a different set of data; for us a new psychic material places itself between the dream-content and the results of our investigation: the latent dream-content, or dream-thoughts, which axe obtained only by our method. We develop the solution of the dream from this latent content, and not from the manifest dream-content. We are thus confronted with a new problem, an entirely novel task — that of examing and tracing the relations between the latent dream thoughts and the manifest dream-content, and the processes by which the latter has grown out of the former.
The dream-thoughts and the dream-content present themselves as two descriptions of the same content in two different languages; or, to put it more clearly, the dream-content appears to us as a translation of the dream-thoughts into another mode of expression, whose symbols and laws of composition we must learn by comparing the origin with the translation. The drearn thoughts we can understand without further trouble the moment we have discovered them. The dream-content is, as it were, presented in hieroglyphics(象形文字), whose symbols must be translated, one by one, into the language of the dream-thoughts. It would of course be incorrect to attempt to read these symbols in accordance with their values as pictures, instead of in accordance with their meaning as symbols.

Of the dream-content and the dream-thoughts, which is the origin ？（）
