psychological theory of the dream and of the psychosis is to be found.)
"Absurd combinations of ideas and weakness of judgment are the main characteristics of the dream and of insanity." The over-estimation of one's own mental capacity, which appears absurd to sober judgment, is found alike both in one and the other, and the rapid course of ideas in the dream corresponds to the flight of ideas in the psychosis. Both are devoid of any measure of time. The dissociation of personality in the dream, which, for instance, distributes one's own knowledge between two persons, one of whom, the strange one, corrects in the dream one's own ego, fully corresponds to the well-known splitting of personality in hallucinatory paranoia; the dreamer, too, hears his own thoughts expressed by strange voices. Even the constant delusions find their analogy in the stereotyped recurring pathological dreams (rêve obsedant). After recovering from a delirium, patients not infrequently declare that the disease appeared to them like an uncomfortable dream; indeed, they inform us that occasionally, even during the course of their sickness, they have felt that they were only dreaming, just as it frequently happens in the sleeping dream.
Considering all this, it is not surprising that Radestock condenses his own opinion and that of many others into the following: Insanity, an abnormal phenomenon of disease, is to be regarded as an enhancement of the periodically recurring normal dream states" (p. 228).
Krauss39 attempted to base the relationship between the dream and insanity upon the etiology (or rather upon the exciting sources), perhaps making the relationship even more intimate than was possible through the analogy of the phenomena they manifest. According to him, the fundamental element common to both is, as we have learned, the organically determined sensation, the sensation of physical stimuli, the general feeling produced by contributions from all the organs. Cf. Peise, cited by Maury48 (p. 60).
The incontestable agreement between the dream and mental disturbance, extending into characteristic details, constitutes one of the strongest supports of the medical theory of dream life, according to which the dream is represented as a
