It is less easy for us to say what the author of _Gradiva_ intended by this dream, and what caused him to connect the development of this delusion directly with a dream. Assiduous investigation of dreams has, to be sure, gathered enough examples of the fact that mental disturbance is connected with and proceeds from dreams,[7] and even in the life-history of certain eminent men, impulses for important deeds and decisions are said to have been engendered by dreams; but our comprehension does not gain much by these analogies; let us hold, therefore, to our case, the case of the archæologist, Norbert Hanold, a fiction of our author. At which end must one lay hold of such a dream to introduce meaning into it, if it is not to remain an unnecessary adornment of fiction? I can imagine that the reader exclaims at this place: “The dream is, of course, easy to explain—a simple anxiety-dream, caused by the noise of the metropolis, which is given the new interpretation of the destruction of Pompeii, by the archæologist busied with his Pompeiian girl!” On account of the commonly prevailing disregard of the activities of dreams, one usually limits the demands for dream-explanations so that one seeks for a part of the dream-content an external excitation which covers itself by means of the content. This external excitation for the dream would be given by the noise which wakens the sleeper; the interest in this dream would be thereby terminated. Would that we had even one reason to suppose that the metropolis had been noisier than usual on this morning! If, for example, our author had not omitted to inform us that Hanold had that night, contrary to his custom, slept by an open window! What a shame that our author didn’t take the trouble! And if an anxiety-dream were only so simple a thing! No, this interest is not terminated in so simple a way. The connection with the external, sensory stimulus is not at all essential for the dream-formation. The sleeper can neglect this excitation from the outer world; he may be awakened by it without forming a dream, he may also weave it into his dream, as happens here, if it is of no use to him from any other motive; and there is an abundance of dreams for whose content such a determination by a sensory excitation of the sleeper cannot be shown. No, let us try another way.
