The Collected Works of Sigmund Freud. Sigmund Freud

of the dream from the mental disturbances, as it is generally known in what unsatisfactory state our understanding of the origin of the latter remains. It is very probably, however, that a modified conception of the dream must also influence our views in regard to the inner mechanism of mental disturbances, and hence we may say that we are engaged in the elucidation of the psychosis when we endeavour to clear up the mystery of the dream.

      I shall have to justify myself for not extending my summary of the literature of the dream problems over the period between the first appearance of this book and its second edition. If this justification may not seem very satisfactory to the reader, I was nevertheless influenced by it. The motives which mainly induced me to summarise the treatment of the dream in the literature have been exhausted with the foregoing introduction; to have continued with this work would have cost me extraordinary effort and would have afforded little advantage or knowledge. For the period of nine years referred to has yielded nothing new or valuable either for the conception of the dream in actual material or in points of view. In most of the publications that have since appeared my work has remained unmentioned and unregarded; naturally least attention has been bestowed upon it by the so-called "investigators of dreams," who have thus afforded a splendid example of the aversion characteristic of scientific men to learning something new. "Les savants ne sont pas curieux," said the scoffer Anatole France. If there were such a thing in science as right to revenge, I in turn should be justified in ignoring the literature since the appearance of this book. The few accounts that have appeared in scientific journals are so full of folly and misconception that my only possible answer to my critics would be to request them to read this book over again. Perhaps also the request should be that they read it as a whole.

      In the works of those physicians who make use of the psychoanalytic method of treatment (Jung, Abraham, Riklin, Muthmann, Stekel, Rank, and others), an abundance of dreams have been reported and interpreted in accordance with my instructions. In so far as these works go beyond the confirmation of my assertions I have noted their results in the context of my discussion. A supplement to the literary index at the end of this book brings together the most important of these new publications. The voluminous book on the dream by Sante de Sanctis, of which a German translation appeared soon after its publication, has, so to speak, crossed with mine, so that I could take as little notice of him as the Italian author could of me. Unfortunately, I am further obliged to declare that this laborious work is exceedingly poor in ideas, so poor that one could never divine from it the existence of the problems treated by me.

I have finally to mention two publications which show a near relation to my treatment of the dream problems. A younger philosopher, H. Swoboda, who has undertaken to extend W. Fliesse's discovery of biological periodicity (in groups of twenty-three and twenty-eight days) to the psychic field, has produced an imaginative work,¹³ in which, among other things, he has used this key to solve the riddle of the dream. The interpretation of dreams would herein have fared badly; the material contained in dreams would be explained through the coincidence of all those memories which during the night complete one of the biological periods for the first or the n-th time. A personal statement from the author led me to assume that he himself no longer wished to advocate this theory earnestly. But it seems I was mistaken in this conclusion; I shall report in another place some observations in reference to Swoboda's assertion, concerning the conclusions of which I am, however, not convinced. It gave me far greater pleasure to find accidentally, in an unexpected place, a conception of the dream in essentials fully agreeing with my own. The circumstances of time preclude the possibility that this conception was influenced by a reading of my book; I must therefore greet this as the only demonstrable concurrence in the literature with the essence of my dream theory. The book which contains the passage concerning the dream which I have in mind was published as a second edition in 1900 by Lynkus under the title Phantasien eines Realisten.

      2. Compare, on the other hand, O. Gruppe, Griechische Mythologie und Religionsgeschichte, p. 390. "Dreams were divided into two classes; the first were influenced only by the present (or past), and were unimportant for the future: they embraced the ένύπνια, insomnia, which immediately produces the given idea or its opposite, e.g. hunger or its satiation, and the φαντάσματα, which elaborates the given idea phantastically, as e.g. the nightmare, ephialtes. The second class was, on the other hand, determinant for the future. To this belong: (1) direct prophecies received in the dream (χρηματωμδς, oraculum); (2) the foretelling of a future event (ὅραμα); (3) the symbolic or the dream requiring interpretation (ὅνειρος, somnium). This theory has been preserved for many centuries."

      3. From subsequent experience I am able to state that it is not at all rare to find in dreams repetitions of harmless or unimportant occupations of the waking state, such as packing trunks, preparing food, work in the kitchen, &c., but in such dreams the dreamer himself emphasizes not the character but the reality of the memory, "I have really done all this in the day time."

4. Chauffeurs were bands of robbers in the Vendée who resorted to this form of torture.

      5. Gigantic persons in a dream justify the assumption that it deals with a scene from the dreamer's childhood.

      6. The first volume of this Norwegian author, containing a complete description of dreams, has recently appeared in German. See Index of Literature, No. 74 a.

      7. Periodically recurrent dreams have been observed repeatedly. Cf. the collection of Chabaneix.¹¹

      8. Silberer has shown by nice examples how in the state of sleepiness even abstract thoughts may be changed into illustrative plastic pictures which express the same thing (Jahrbuch von Bleuler-Freud, vol. i. 1900).

      9. Haffner³² made an attempt similar to Delb{{subst:oe}}uf's to explain the dream activity on the basis of an alteration which must result in an introduction of an abnormal condition in the otherwise correct function of the intact psychic apparatus, but he described this condition in somewhat different words. He states that the first distinguishing mark of the dream is the absence of time and space, i.e. the emancipation of the presentation from the position in the order of time and space which is common to the individual. Allied to this is the second fundamental character of the dream, the mistaking of the hallucinations, imaginations, and phantasy-combinations for objective perceptions. The sum total of the higher psychic forces, especially formation of ideas, judgment, and argumentation on the one hand, and the free self-determination on the other hand, connect themselves with the sensory phantasy pictures and at all times have them as a substratum. These activities too, therefore, participate in the irregularity of the dream presentation. We say they participate, for our faculties of judgment and will power are in themselves in no way altered during sleep. In reference to activity, we are just as keen and just as free as in the waking state. A man cannot act contrary to the laws of thought, even in the dream, i.e. he is unable to harmonise with that which represents itself as contrary to him, &c.; he can only desire in the dream that which he presents to himself as good (sub ratione boni). But in this application of the laws of thinking and willing the human mind is led astray in the dream through mistaking one presentation for another. It thus happens that we form and commit in the dream the greatest contradictions, while, on the other hand, we display the keenest judgments and the most consequential chains of reasoning, and can make the most virtuous and sacred resolutions. Lack of orientation is the whole secret of the flight by which our phantasy moves in the dream, and lack of critical reflection and mutual understanding with others is the main source of
