“To him who is tortured by physical and mental sufferings the dream accords what has been denied him by reality, to wit, physical well-being and happiness; so the insane, too, see the bright pictures of happiness, greatness, sublimity, and riches. The supposed possession of estates and the imaginary fulfilment of wishes, the denial or destruction of which have just served as a psychic cause of the insanity, often form the main content of the delirium. The woman who has lost a dearly beloved child, in her delirium experiences maternal joys; the man who has suffered reverses of fortune deems himself immensely wealthy; and the jilted girl pictures herself in the bliss of tender love.” The above passage from Radestock, an abstract of a keen discussion of Griesinger[31] (p. 111), reveals with the greatest clearness the wish fulfilment as a characteristic of the imagination, common to the dream and the psychosis. (My own investigations have taught me that here the key to a 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 obsédant_). 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).
