The collected reminiscences are called the “dream material.” We treat this material by a universally valid scientific method. If you ever have to work up experimental material, you compare the individual units and classify them according to similarities. You proceed exactly in the same way with dream-material; you look for the common traits either of a formal or a substantial nature.
Certain extremely common prejudices must be got rid of. I have always noticed that the beginner is looking for one trait or another and tries to make his material conform to his expectation. This condition I noticed especially among those colleagues who were formerly more or less passionate opponents of psychoanalysis, their opposition being based on well-known prejudices and misunderstandings. When I had the chance of analyzing them, whereby they obtained at last a real insight into the method, the first mistake generally made in their own psychoanalytic work was that they did violence to the material by their own preconceived opinion. They gave vent to their former prejudice against psychoanalysis in their attitude towards the material, which they could not estimate objectively, but only according to their subjective phantasies.
If one would have the courage to sift dream material, one must not recoil from any parallel. The dream material generally consists of very heterogeneous associations, out of which it is sometimes very difficult to deduce the tertium comparationis. I refrain from giving detailed examples, as it is quite impossible to handle in a lecture the voluminous material of a dream. I might call your attention to Rank’s[[9]] article in the Jahrbuch, “Ein Traum der sich selber deutet” (A dream interpreted by itself). There you will see what an extensive material must be taken into consideration for comparison.
Hence, for the interpretation of the unconscious we proceed in the same way as is universal when a conclusion is to be drawn by classifying material. The objection is very often heard: Why does the dream have an unconscious content at all? In my view, this objection is as unscientific as possible. Every actual psychological moment has its special history. Every sentence I pronounce has, beside the intended meaning known to me another historical meaning, and it is possible that its second meaning is entirely different from its conscious meaning. I express myself on purpose somewhat paradoxically. I do not mean that I could explain every individual sentence in its historical meaning. This is a thing easier to do in larger and more detailed contributions. It will be clear to everyone, that a poem is, apart from its manifest content, especially characteristic of the poet in regard to its form, its content, and its manner of origin. Although the poet, in his poem, gave expression to the mood of a moment, the literary historian will find things in it and behind it which the poet never foresaw. The analysis which the literary historian draws from the poet’s material is exactly the method of psychoanalysis.
The psychoanalytic method, generally speaking, can be compared with historical analysis and synthesis. Suppose, for instance, we did not understand the meaning of baptism as practised in our churches to-day. The priest tells us the baptism means the admission of the child into the Christian community. But this does not satisfy us. Why is the child sprinkled with water? To understand this ceremony, we must choose out of the history of rites, those human traditions which pertain to this subject, and thus we get material for comparison, to be considered from different standpoints.
I. The baptism means obviously an initiation ceremony, a consecration; therefore all the traditions containing initiation rites have to be consulted.
II. The baptism takes place with water. This special form requires another series of traditions, namely, those rites where water is used.
III. The person to be baptized is sprinkled with water. Here are to be consulted all those rites where the initiated is sprinkled or submerged, etc.
IV. All the reminiscences of folklore, the superstitious practices must be remembered, which in any way run parallel with the symbolism of the baptismal act.
In this way, we get a comparative scientific study of religion as regards baptism. We accordingly discover the different elements out of which the act of baptism has arisen. We ascertain further its original meaning, and we become at the same time acquainted with the rich world of myths that have contributed to the foundations of religions, and thus we are enabled to understand the manifold and profound meanings of baptism. The analyst proceeds in the same way with the dream. He collects the historical parallels to every part of the dream, even the remotest, and he tries to reconstruct the psychological history of the dream, with its fundamental meaning, exactly as in the analysis of the act of baptism. Thus, through the monographic treatment of the dream, we get a profound and beautiful insight into that mysterious, fine and ingenious network of unconscious determination. We get an insight, which as I said before, can only be compared with the historical understanding of any act which we had hitherto regarded in a superficial and one-sided way.
