Part 7

The dream therefore thinks preponderately, but not exclusively, in visual pictures. It also makes use of auditory pictures, and to a lesser extent of the impressions of the other senses. Much is also simply thought or imagined (probably represented by remnants of word presentations), just as in the waking state. But still what is characteristic for the dream is only those elements of the content which act like pictures, i.e. which resemble more the perceptions than the memory presentations. Disregarding all the discussions concerning the nature of hallucinations, familiar to every psychiatrist, we can say, with all well-versed authors, that the dream hallucinates, that is, replaces thoughts through hallucinations. In this respect there is no difference between visual and acoustic presentations; it has been noticed that the memory of a succession of sounds with which one falls asleep becomes transformed while sinking into sleep into an hallucination of the same melody, so as to make room again on awakening, which may repeatedly alternate with falling into a slumber, for the softer memory presentations which are differently formed in quality.

The transformation of an idea into an hallucination is not the only deviation of the dream from a waking thought which perhaps corresponds to it. From these pictures the dream forms a situation, it presents something in the present, it dramatises an idea, as Spitta (p. 145) puts it. But the characteristic of this side of the dream life becomes complete only when it is remembered that while dreaming we do not—as a rule; the exceptions require a special explanation—imagine that we are thinking, but that we are living through an experience, i.e., we accept the hallucination with full belief. The criticism that this has not been experienced but only thought in a peculiar manner—dreamt—comes to us only on awakening. This character distinguishes the genuine sleeping dream from day dreaming, which is never confused with reality.

The characteristics of the dream life thus far considered have been summed up by Burdach (p. 476) in the following sentences: “As characteristic features of the dream we may add (a) that the subjective activity of our mind appears as objective, inasmuch as our faculty of perception perceives the products of phantasy as if they were sensory activities ... (b) sleep abrogates one’s self-command, hence falling asleep necessitates a certain amount of passivity.... The slumber pictures are conditioned by the relaxation of one’s self-command.”

It is a question now of attempting to explain the credulity of the mind in reference to the dream hallucinations, which can only appear after the suspension of a certain arbitrary activity. Strümpell asserts that the mind behaves in this respect correctly, and in conformity with its mechanism. The dream elements are by no means mere presentations, but true and real experiences of the mind, similar to those that appear in the waking state as a result of the senses (p. 34). Whereas in the waking state the mind represents and thinks in word pictures and language, in the dream it represents and thinks in real tangible pictures (p. 35). Besides, the dream manifests a consciousness of space by transferring the sensations and pictures, just as in the waking state, into an outer space (p. 36). It must therefore be admitted that the mind in the dream is in the same relation to its pictures and perceptions as in the waking state (p. 43). If, however, it is thereby led astray, this is due to the fact that it lacks in sleep the criticism which alone can distinguish between the sensory perceptions emanating from within or from without. It cannot subject its pictures to the tests which alone can prove their objective reality. It furthermore neglects to differentiate between pictures that are arbitrarily interchanged and others where there is no free choice. It errs because it cannot apply to its content the law of causality (p. 58). In brief, its alienation from the outer world contains also the reason for its belief in the subjective dream world.

Delbœuf reaches the same conclusion through a somewhat different line of argument. We give to the dream pictures the credence of reality because in sleep we have no other impressions to compare them with, because we are cut off from the outer world. But it is not perhaps because we are unable to make tests in our sleep, that we believe in the truth of our hallucinations. The dream may delude us with all these tests, it may make us believe that we may touch the rose that we see in the dream, and still we only dream. According to Delbœuf there is no valid criterion to show whether something is a dream or a conscious reality, except—and that only in practical generality—the fact of awakening. “I declare delusional everything that is experienced between the period of falling asleep and awakening, if I notice on awakening that I lie in my bed undressed” (p. 84). “I have considered the dream pictures real during sleep in consequence of the mental habit, which cannot be put to sleep, of perceiving an outer world with which I can contrast my ego.”

As the deviation from the outer world is taken as the stamp for the most striking characteristics of the dream, it will be worth while mentioning some ingenious observations of old Burdach which will throw light on the relation of the sleeping mind to the outer world and at the same time serve to prevent us from over-estimating the above deductions. “Sleep results only under the condition,” says Burdach, “that the mind is not excited by sensory stimuli ... but it is not the lack of sensory stimuli that conditions sleep, but rather a lack of interest for the same; some sensory impressions are even necessary in so far as they serve to calm the mind; thus the miller can fall asleep only when he hears the rattling of his mill, and he who finds it necessary to burn a light at night, as a matter of precaution, cannot fall asleep in the dark” (p. 457).

“The psyche isolates itself during sleep from the outer world, and withdraws from the periphery.... Nevertheless, the connection is not entirely interrupted; if one did not hear and feel even during sleep, but only after awakening, he would certainly never awake. The continuance of sensation is even more plainly shown by the fact that we are not always awakened by the mere sensory force of the impression, but by the psychic relation of the same; an indifferent word does not arouse the sleeper, but if called by name 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): “Il 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 elles-mêmes 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 chorée 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, positively admits this. One might inquire as to the kind and behaviour of the remnants of the psychic life which manifest themselves in the dream. It is now quite universally acknowledged that the reproductive capacity, the memory in the dream, seems to have been least affected; indeed it may show a certain superiority over the same function in the waking life (vid. supra, p. 10), although a part of the absurdities of the dream are to be explained by just this forgetfulness of the dream life. According to Spitta, it is the emotional life of the psyche that is not overtaken by sleep and that then directs the dream. “By emotion [“Gemüth”] we understand the constant comprehension of the feelings as the inmost subjective essence of man” (p. 84).

Scholz (p. 37) sees a psychic activity manifested in the dream in the “allegorising interpretation” to which the dream material is subjected. Siebeck verifies also in the dream the “supplementary interpretative activity” (p. 11) which the mind exerts on all that is perceived and viewed. The judgment of the apparently highest psychic function, the consciousness, presents for the dream a special difficulty. As we can know anything only through consciousness, there can be no doubt as to its retention; Spitta, however, believes that only consciousness is retained in the dream, and not self-consciousness. Delbœuf confesses that he is unable to conceive this differentiation.

The laws of association which govern the connection of ideas hold true also for the dream pictures; indeed, their domination evinces itself in a purer and stronger expression in the dream than elsewhere. Strümpell (p. 70) says: “The dream follows either the laws of undisguised presentations as it seems exclusively or organic stimuli along with such presentations, that is, without being influenced by reflection and reason, æsthetic sense, and moral judgment.” The authors whose views I reproduce here conceive the formation of the dream in about the following manner: The sum of sensation stimuli affecting sleep from the various sources, discussed elsewhere, at first awaken in the mind a sum of presentations which represent themselves as hallucinations (according to Wundt, it is more correct to say as illusions, because of their origin from outer and inner stimuli). These unite with one another according to the known laws of association, and, following the same rules, in turn evoke a new series of presentations (pictures). This entire material is then elaborated as well as possible by the still active remnant of the organising and thinking mental faculties (cf. Wundt and Weygandt). But thus far no one has been successful in finding the motive which would decide that the awakening of pictures which do not originate objectively follow this or that law of association.
