We call such a constant relationship between a dream element and its interpretation _symbolic_. The dream element is itself a _symbol_ of the unconscious dream thought. You will remember that previously, when we were investigating the relationship between dream elements and their actuality, I drew three distinctions, viz., that of the part of the whole, that of the allusion, and that of the imagery. I then announced that there was a fourth, but did not name it. This fourth is the symbolic relationship here introduced. Very interesting discussions center about this, and we will now consider them before we express our own particular observations on symbolism. Symbolism is perhaps the most noteworthy chapter of dream study. In the first place, since symbols are permanent or constant translations, they realize, in a certain measure, the ideal of ancient as well as popular dream interpretation, an ideal which by means of our technique we had left behind. They permit us in certain cases to interpret a dream without questioning the dreamer who, aside from this, has no explanation for the symbol. If the interpreter is acquainted with the customary dream symbols and, in addition, with the dreamer himself, the conditions under which the latter lives and the impressions he received before having the dream, it is often possible to interpret a dream without further information--to translate it "right off the bat." Such a trick flatters the interpreter and impresses the dreamer; it stands out as a pleasurable incident in the usual arduous course of cross-examining the dreamer. But do not be misled. It is not our function to perform tricks. Interpretation based on a knowledge of symbols is not a technique that can replace the associative technique, or even compare with it. It is a supplement to the associative technique, and furnishes the latter merely with transplanted, usable results. But as regards familiarity with the dreamer's psychic situation, you must consider the fact that you are not limited to interpreting the dreams of acquaintances; that as a rule you are not acquainted with the daily occurrences which act as the stimuli for the dreams, and that the associations of the subject furnish you with a knowledge of that very thing we call the psychic situation.
