7. Manifestations of the Unconscious

Examination of the whole range of the life of dream brings to light two peculiar features which must be particularly borne in mind. The one is that what is usually called logic plays no part in dreams. The dream has a rule entirely different from that of ordinary logic for the way in which it passes from one object to the other. Naturally you will be able to insist that many dreams take a perfectly logical course. But this is only apparently the case, as everyone who can observe these things intimately, knows. If dream-pictures present themselves in logical sequence, the reason is not that you yourself produce this sequence during the dream but that you are placing side by side, mental images which you have already connected together logically at some time or which have been so connected by some agency in life. In such a case, logic in the dream is reminiscence; the logic has been imported into the dream; the action of the dream does not in itself proceed according to the rules of ordinary logic.
