he awakens...: hence the psyche differentiates sensations during sleep.... It is for this reason that we may be awakened by the lack of a sensory stimulus if it relates to the presentation of an important thing; thus one awakens when the light is extinguished, and the miller when the mill comes to a standstill; that is, the awakening is due to the cessation of a sensory activity, which presupposes that it has been perceived, and that it has not disturbed the mind, being indifferent or rather gratifying" (p. 460, &c.).
If we are willing to disregard these objections, which are not to be taken lightly, we still must admit that the qualities of the dream life thus far considered, which originate by withdrawing from the outer world, cannot fully explain the strangeness of the dream. For otherwise it would be possible to change back the hallucinations of the dream into presentations and the situations of the dream into thoughts, and thus to perform the task of dream interpretation. Now this is what we do when we reproduce the dream from memory after awakening, and whether we are fully or only partially successful in this back translation the dream still retains its mysteriousness undiminished.
Furthermore all the authors assume unhesitatingly that still other more far-reaching alterations take place in the presentation material of waking life. One of them, Strümpell, expresses himself as follows (p. 17): "With the cessation of the objectively active outlook and of the normal consciousness, the psyche loses the foundation in which were rooted the feelings, desires, interests, and actions. Those psychic states, feelings, interests, estimates which cling in the waking state to the memory pictures also succumb to... an obscure pressure, in consequence of which their connection with the pictures becomes severed; the perception pictures of things, persons, localities, events, and actions of the waking state are singly very abundantly reproduced, but none of these brings along its psychic value. The latter is removed from them, and hence they float about in the mind dependent upon their own resources...."
This deprivation the picture suffers of its psychic value, which again goes back to the derivation from the outer world, is according to Strümpell mainly responsible for the impression of strangeness with which the dream is confronted in our memory.
We have heard that even falling asleep carries with it the abandonment of one of the psychic activities—namely, the voluntary conduct of the presentation course. Thus the supposition, suggested also by other grounds, obtrudes itself, that the sleeping state may extend its influence also over the psychic functions. One or the other of these functions is perhaps entirely suspended; whether the remaining ones continue to work undisturbed, whether they can furnish normal work under the circumstances, is the next question. The idea occurs to us that the peculiarities of the dream may be explained through the inferior psychic activity during the sleeping state, but now comes the impression made by the dream upon our waking judgment which is contrary to such a conception. The dream is disconnected, it unites without hesitation the worst contradictions, it allows impossibilities, it disregards our authoritative knowledge from the day, and evinces ethical and moral dulness. He who would behave in the waking state as the dream does in its situations would be considered insane. He who in the waking state would speak in such manner or report such things as occur in the dream content, would impress us as confused and weak-minded. Thus we believe that we are only finding words for the fact when we place but little value on the psychic activity in the dream, and especially when we declare that the higher intellectual activities are suspended or at least much impaired in the dream.
With unusual unanimity—the exceptions will be dealt with elsewhere—the authors have pronounced their judgments on the dream—such judgments as lead immediately to a definite theory or explanation of the dream life. It is time that I should supplement the résumé which I have just given with a collection of the utterances of different authors—philosophers and physicians—on the psychological character of the dream.
According to Lemoine, the incoherence of the dream picture is the only essential character of the dream.
Maury agrees with him; he says (p. 163) : "II n'y a pas des rêves absolument raisonnables et qui ne contiennent quelque incohérence, quelque anachronisme, quelque absurdité."
According to Hegel, quoted by Spitta, the dream lacks all objective and comprehensible connection.
Dugas says: "Le rêve, c'est l'anarchie psychique, affective et mentale, c'est le jeu des fonctions livrées à ellesmêmes et s'exerçant sans contrôle et sans but; dans le rêve l'esprit est un automate spirituel."
"The relaxation, solution, and confusion of the presentation life which is held together through the logical force of the central ego" is conceded even by Volkelt (p. 14), according to whose theory the psychic activity during sleep seems in no way aimless.
The absurdity of the presentation connections appearing in the dream can hardly be more strongly condemned than it was by Cicero (De Divin. II.): "Nihil tam praepostere, tam incondite, tam monstruose cogitari potest, quod non possimus somniare."
Fechner says (p. 522): "It is as if the psychological activity were transferred from the brain of a reasonable being into the brain of a fool."
Radestock (p. 145) says: "It seems indeed impossible to recognise in this absurd action any firm law. Having withdrawn itself from the strict police of the rational will guiding the waking presentation life, and of the attention, the dream whirls everything about kaleidoscopically in mad play."
Hildebrandt (p. 45) says: "What wonderful jumps the dreamer allows himself, e.g., in his chain of reasoning! With what unconcern he sees the most familiar laws of experience turned upside down! What ridiculous contradictions he can tolerate in the orders of nature and society before things go too far, as we say, and the overstraining of the nonsense brings an awakening! We often multiply quite unconcernedly: three times three make twenty; we are not at all surprised when a dog recites poetry for us, when a dead person walks to his grave, and when a rock swims on the water; we go in all earnestness by high command to the duchy of Bernburg or the principality of Lichtenstein in order to observe the navy of the country, or we allow ourselves to be recruited as a volunteer by Charles XII. shortly before the battle of Poltawa."
Binz (p. 33) points to a dream theory resulting from the impressions. "Among ten dreams nine at least have an absurd content. We unite in them persons or things which do not bear the slightest relation to one another. In the next moment, as in a kaleidoscope, the grouping changes, if possible to one more nonsensical and irrational than before; thus the changing play of the imperfectly sleeping brain continues until we awaken, and put our hand to our forehead and ask ourselves whether we really still possess the faculty of rational imagination and thought."
Maury (p. 50) finds for the relation of the dream picture to the waking thoughts, a comparison most impressive for the physician: "La production de ces images que chez l'homme éveillé fait le plus souvent naître la volonté, correspond, pour l'intelligence, à ce que cont pour la motilité certains mouvements que nous offrent la choreé et les affections paralytiques...." For the rest, he considers the dream "toute une série de dégradation de la faculté pensant et raisonant" (p. 27).
It is hardly necessary to mention the utterances of the authors which repeat Maury's assertion for the individual higher psychic activities.
According to Strümpell, some logical mental operations based on relations and connections disappear in the dream—naturally also at points where the nonsense is not obvious (p. 26). According to Spitta, (p. 148) the presentations in the dream are entirely withdrawn from the laws of causality. Radestock and others emphasize the weakness of judgment and decision in the dream. According to Jodl (p. 123), there is no critique in the dream, and no correcting of a series of perceptions through the content of the sum of consciousness. The same author states that "all forms of conscious activity occur in the dream, but they are imperfect, inhibited, and isolated from one another." The contradictions manifested in the dream towards our conscious knowledge are explained by Stricker (and many others), on the ground that facts are forgotten in the dream and logical relations between presentations are lost (p. 98), &c., &c.
The authors who in general speak thus unfavourably about the psychic capacities in the dream, nevertheless admit that the dream retains a certain remnant of psychic activity. Wundt, whose teaching has influenced so many other workers in the dream problems,
