of the things of real interest. In answering the question as to what provokes the dream, as to the connection of the dream, in the daily troubles, we must say, in terms of the insight givenus by replacing the manifest latent dream content: The dream does never trouble itself about things which are not deserving of our concern during the day, and trivialities which do not trouble us during the day have no power to pursue us whilst asleep.
What provoked the dream in the example which we have analyzed? The really unimportant event, that a friend invited me to a free ride in his cab. The table d'hote scene in the dream contains an allusion to this indifferent motive, for in conversation I had brought the taxi parallel with the table d'hote. But I can indicate the important event which has as its substitute the trivial one. A few days before I had disbursed a large sum of money for a member of my family who is very dear to me. Small wonder, says the dream thought, if this person is grateful to me for this--this love is not cost-free. But love that shall cost nothing is one of the prime thoughts of the dream. The fact that shortly before this I had had several drives with the relative in question puts the one drive
with my friend in a position to recall the connection with the other person. The indifferent impression which, by such ramifications,
provokes the dream is subservient to another condition which is not true of the real source of the dream--the impression must be a
recent one, everything arising from the day of the dream.
I cannot leave the question of dream displacement without the consideration of a remarkable process in the formation of dreams in which condensation and displacement work together towards one end. In condensation we have already considered the case where two conceptions in the dream having something in common, some point of contact, are replaced in the dream content by a mixed image, where the distinct germ corresponds to what is common, and the indistinct secondary modifications to what is distinctive. If displacement is added to condensation, there is no formation of a mixed image, but a common mean which bears the same relationship to the individual elements as does the resultant in the parallelogram of forces to its components. In one of my dreams, for instance, there is talk of an injection with propyl. On first analysis I discovered an indifferent but true incident where amyl played a part as the excitant of the dream. I cannot yet vindicate the exchange of amyl for propyl. To the round of ideas of the same dream, however, there belongs the recollection of my first visit to Munich, when the Propyloea struck me. The attendant circumstances of the analysis render it admissible that the influence of this second group of conceptions caused the displacement of amyl to propyl. Propyl is, so to say, the mean idea between amyl and propyloea; it got into the dream as a kind of compromise by simultaneous condensation and displacement.
The need of discovering some motive for this bewildering work of the dream is even more called for in the case of displacement than in condensation.
Although the work of displacement must be held mainly responsible if the dream thoughts are not refound or recognized in the dream content (unless the motive of the changes be guessed), it is another and milder kind of transformation which will be considered with the dream thoughts which leads to the discovery of a new but readily understood act of the dream work. The first dream thoughts which are unravelled by analysis frequently strike one by their unusual wording. They do not appear to be expressed in the sober form which our thinking prefers; rather are they expressed symbolically by allegories and metaphors like the figurative language of the poets. It is not difficult to find the motives for this degree of constraint in the expression of dream ideas. The dream content consists chiefly of visual scenes; hence the dream ideas must, in the first place, be prepared to make use of these forms of presentation. Conceive that a political leader's or a barrister's address had to be transposed into pantomime, and it will be easy to understand the transformations to which the dream work is constrained by regard for this dramatization of the dream content.
Around the psychical stuff of dream thoughts there are ever found reminiscences of impressions, not infrequently of early child-
hood--scenes which, as a rule, have been visually grasped. Whenever possible, this portion of the dream ideas exercises a definite in-
12
fluence upon the modelling of the dream content; it works like a center of crystallization, by attracting and rearranging the stuff of the dream thoughts. The scene of the dream is not infrequently nothing but a modified repetition, complicated by interpolations of events that have left such an impression; the dream but very seldom reproduces accurate and unmixed reproductions of real scenes.
The dream content does not, however, consist exclusively of scenes, but it also includes scattered fragments of visual images, conversations, and even bits of unchanged thoughts. It will be perhaps to the point if we instance in the briefest way the means of dramatization which are at the disposal of the dream work for the repetition of the dream thoughts in the peculiar language of the dream.
The dream thoughts which we learn from the analysis exhibit themselves as a psychical complex of the most complicated super-structure. Their parts stand in the most diverse relationship to each other; they form backgrounds and foregrounds, stipulations, digressions, illustrations, demonstrations, and protestations. It may be said to be almost the rule that one train of thought is followed by its contradictory. No feature known to our reason whilst awake is absent. If a dream is to grow out of all this, the psychical matter is submitted to a pressure which condenses it extremely, to an inner shrinking and displacement, creating at the same time fresh surfaces, to a selective interweaving among the constituents best adapted for the construction of these scenes. Having regard to the ori-gin of this stuff, the term regression can be fairly applied to this process. The logical chains which hitherto held the psychical stuff together become lost in this transformation to the dream content. The dream work takes on, as it were, only the essential content of the dream thoughts for elaboration. It is left to analysis to restore the connection which the dream work has destroyed.
The dream's means of expression must therefore be regarded as meager in comparison with those of our imagination, though the dream does not renounce all claims to the restitution of logical relation to the dream thoughts. It rather succeeds with tolerable frequency in replacing these by formal characters of its own.
By reason of the undoubted connection existing between all the parts of dream thoughts, the dream is able to embody this matter into a single scene. It upholds a logical connection as approximation in time and space, just as the painter, who groups all the poets for his picture of Parnassus who, though they have never been all together on a mountain peak, yet form ideally a community. The dream continues this method of presentation in individual dreams, and often when it displays two elements close together in the dream content it warrants some special inner connection between what they represent in the dream thoughts. It should be, moreover, observed that all the dreams of one night prove on analysis to originate from the same sphere of thought.
The causal connection between two ideas is either left without presentation, or replaced by two different long portions of dreams one after the other. This presentation is frequently a reversed one, the beginning of the dream being the deduction, and its end the hypothesis. The direct transformation of one thing into another in the dream seems to serve the relationship of cause and effect.
The dream never utters the alternative "either-or," but accepts both as having equal rights in the same connection. When "either-or"
is used in the reproduction of dreams, it is, as I have already mentioned, to be replaced by "and."
Conceptions which stand in opposition to one another are preferably expressed in dreams by the same element.2 There seems no "not" in dreams. Opposition between two ideas, the relation of conversion, is represented in dreams in a very remarkable way. It is expressed by the reversal of another part of the dream content just as if by way of appendix. We shall later on deal with another
