In some dreams, which adhere for a time to a certain situation and scenery, there occur interruptions described in the following words: “But then it seemed as though it were at the same time another place, and there such and such a thing happened.” What thus interrupts the main trend of the dream, which after a while may be continued again, turns out to be a subordinate idea, an interpolated thought in the dream material. A conditional relation in the dream-thoughts is represented by simultaneousness in the dream (wenn—wann; if—when). What is signified by the sensation of impeded movement, which so often occurs in the dream, and which is so closely allied to anxiety? One wants to move, and is unable to stir from the spot; or one wants to accomplish something, and meets one obstacle after another. The train is about to start, and one cannot reach it; one’s hand is raised to avenge an insult, and its strength fails, &c. We have already encountered this sensation in exhibition dreams, but have as yet made no serious attempt to interpret it. It is convenient, but inadequate, to answer that there is motor paralysis in sleep, which manifests itself by means of the sensation alluded to. We may ask: “Why is it, then, that we do not dream continually of these impeded motions?” And we are justified in supposing that this sensation, constantly appearing in sleep, serves some purpose or other in representation, and is brought about by a need occurring in the dream material for this sort of representation. Failure to accomplish does not always appear in the dream as a sensation, but also simply as a part of the dream content. I believe that a case of this sort is particularly well suited to enlighten us about the significance of this characteristic of the dream. I shall give an abridged report of a dream in which I seem to be accused of dishonesty. _The scene is a mixture, consisting of a private sanatorium and several other buildings. A lackey appears to call me to an examination. I know in the dream that something has been missed, and that the examination is taking place because I am suspected of having appropriated the lost article. Analysis shows that examination is to be taken in two senses, and also means medical examination. Being conscious of my innocence, and of the fact that I have been called in for consultation, I calmly follow the lackey. We are received at the door by another lackey, who says, pointing to me, “Is that the person whom you have brought? Why, he is a respectable man.” Thereupon, without any lackey, I enter a great hall in which machines are standing, and which reminds me of an Inferno with its hellish modes of punishment. I see a colleague strapped on to one apparatus who has every reason to be concerned about me; but he takes no notice of me. Then I am given to understand that I may now go. Then I cannot find my hat, and cannot go after all._
