The Interpretation of Dreams by Sigmund Freud
V. THE MATERIAL AND SOURCES OF DREAMS (continued)

D. Typical Dreams -

Generally speaking, we are not in a position to interpret another person's dream if he is unwilling to furnish us with the unconscious thoughts which lie behind the dream-content, and for this reason the practical applicability of our method of dream- interpretation is often seriously restricted. * But there are dreams which exhibit a complete contrast to the individual's customary liberty to endow his dream-world with a special individuality, thereby making it inaccessible to an alien understanding: there are a number of dreams which almost every one has dreamed in the same manner, and of which we are accustomed to assume that they have the same significance in the case of every dreamer. A peculiar interest attaches to these typical dreams, because, no matter who dreams them, they presumably all derive from the same sources, so that they would seem to be particularly fitted to provide us with information as to the sources of dreams.

* The statement that our method of dream-interpretation is inapplicable when we have not at our disposal the dreamer's association-material must be qualified. In one case our work of interpretation is independent of these associations: namely, when the dreamer make use of symbolic elements in his dream. We then employ what is, strictly speaking, a second auxiliary method of dream-interpretation. (See below).

With quite special expectations, therefore, we shall proceed to test our technique of dream-interpretation on these typical dreams, and only with extreme reluctance shall we admit that precisely in respect of this material our method is not fully verified. In the interpretation of typical dreams we as a rule fail to obtain those associations from the dreamer which in other cases have led us to comprehension of the dream, or else these associations are confused and inadequate, so that they do not help us to solve our problem.

Why this is the case, and how we can remedy this defect in our technique, are points which will be discussed in a later chapter. The reader will then understand why I can deal with only a few of the group of typical dreams in this chapter, and why I have postponed the discussion of the others.
