One is therefore justified in taking the result of this last investigation as an indication of the fact that the satisfactory explanation of the psychologic determinations of faulty and chance actions is to be acquired in another way and from another source. The indulgent reader can therefore see in these discussions the demonstration of the surfaces of fracture in which this theme was quite artificially evolved from a broader connection. VII. Just a few words to indicate the direction of this broader connection. The mechanism of the faulty and chance actions, as we have learned to know it through the application of analysis, shows in the most essential points an agreement with the mechanism of dream formation, which I have discussed in the chapter “The Dream Work” of my book on the interpretation of dreams. Here, as there, one finds the condensation and compromise formation (“contaminations”); in addition the situation is much the same, since unconscious thoughts find expression as modifications of other thoughts in unusual ways and through outer associations. The incongruities, absurdities, and errors in the dream content by virtue of which the dream is scarcely recognized as a psychic achievement originate in the same way--to be sure, through freer usage of the existing material--as the common error of our everyday life; _here, as there, the appearance of the incorrect function is explained through the peculiar interference of two or more correct actions_. An important conclusion can be drawn from, this combination: the peculiar mode of operation, whose most striking function we recognize in the dream content, should not be adjudged only to the sleeping state of the psychic life when we possess abundant proof of its activity during the waking state in the form of faulty actions. The same connection also forbids us assuming that these psychic processes which impress us as abnormal and strange are determined by deep-seated decay of psychic activity or by morbid state of function.[83] The correct understanding of this strange psychic work which allows the faulty actions to originate like the dream pictures will only be possible after we have discovered that the psychoneurotic symptoms, particularly the psychic formations of hysteria and compulsion neurosis, repeat in their mechanisms all the essential features of this mode of operation. The continuation of our investigation would therefore have to begin at this point.
