Henri Bergson

“ Often in the midst of the night the contact of our body with its light clothing makes itself felt all at once and reminds us that we are lightly clothed. Then, if our dream is at the moment taking us through the street, it is in this simple attire that we present ourselves to the gaze of the passers-by, without their appearing to be astonished by it. We are ourselves astonished in the dream, but that never appears to astonish other people. I cite this dream because it is frequent. ”

“ What is sleep? I do not ask, of course, how sleep can be explained physiologically. That is a special question, and besides is far from being settled. I ask what is sleep psychologically; for our mind continues to exercise itself when we are asleep, and it exercises itself as we have just seen on elements analogous to those of waking, on sensations and memories; and also in an analogous manner combines them. Nevertheless we have on the one hand normal perception, and on the other the dream. ”

“ Then these memories, perceiving that I have taken away the obstacle, have raised the trapdoor which has kept them beneath the floor of consciousness, arise from the depths; they rise, they move, they perform in the night of unconsciousness a great dance macabre. ”

“ The body, which does not come altogether viable from the hand of nature, rises toward the soul which might give it complete life; and the soul, looking upon the body and believing that it perceives its own image as in a mirror, and attracted, fascinated by the image, lets itself fall. It falls, and this fall is life. I may compare to these detached souls the memories plunged in the obscurity of the unconscious. On the other hand, our noc [Pg 37] turnal sensations resemble these incomplete bodies. The sensation is warm, colored, vibrant and almost living, but vague. ”

“ The rôle of the brain is to bring back the remembrance of an action, to prolong the remembrance in movements. If one could see all that takes place in the interior of the brain, one would find that that which takes place there corresponds to a small part only of the life of the mind. The brain simply extracts from the life of the mind that which is capable of representation in movement. The cerebral life is to the mental life what the movements of the baton of a conductor are to the Symphony. ”

“ This is the idea that we can explore the unconscious substratum of our mentality, the storehouse of our memories, by means of dreams, for these memories are by no means inert, but have, as it were, a life and purpose of their own, and strive to rise into consciousness whenever they get a chance, even into the semi-consciousness of a dream. To use Professor Bergson's striking metaphor, our memories are packed away under pressure like steam in a boiler and the dream is their escape valve. ”

“ Our senses continue to be active. They act, it is true, with less precision, but in compensation they embrace a host of "subjective" impressions which pass unperceived when we are awake—for then we live in a world of perceptions common to all men—and which reappear in sleep, when we live only for ourselves. Thus our faculty of sense perception, far from being narrowed during sleep at all points, is on the contrary extended, at least in certain directions, in its field of operations. It is true that it often loses in energy, in tension, what it gains in extension. ”

“ When this union is effected between the memory and the sensation, we have a dream.
In a poetic page of the Enneades, the [Pg 36] philosopher Plotinus, interpreter and continuator of Plato, explains to us how men come to life. Nature, he says, sketches the living bodies, but sketches them only. Left to her own forces she can never complete the task. On the other hand, souls inhabit the world of Ideas. Incapable in themselves of acting, not even thinking of action, they float beyond space and beyond time. ”

“ A universe wound up once for all and doing nothing thereafter but mark time is as incomprehensible to him as a universe that never had a mind of its own and knows no difference between past and future. ”

“ In place of attaching myself to life, I detach myself from it. Everything has become indifferent to me. I have become disinterested in everything. To sleep is to become disinterested. One sleeps to the exact extent to which he becomes disinterested. A mother who sleeps by the side of her child will not stir at the sound of thunder, but the sigh of the child will wake her. Does she really sleep in regard to her child? We do not sleep in regard to what continues to interest us. [Pg 49]
"You ask me what it is that I do when I dream? ”

“ To connect the sound of a barking dog with the memory of a crowd that murmurs and shouts requires no effort. But in order that this sound should be perceived as the barking of a dog, a positive effort must be made. It is this force that the dreamer lacks. ”

“ You exert, then, continually, every moment of the day, an enormous effort. Your life in a waking state is a life of labor, even when you think you are doing nothing, for at every minute you have to choose and every minute exclude. You choose among your sensations, since you reject from your consciousness a thousand subjective sensations which come back in the night when you sleep. You choose, and with extreme precision and delicacy, among [Pg 48] your memories, since you reject all that do not exactly suit your present state. ”

“ I should dream of the cure, in any case, more probably than that I should dream of the disease. In short, the events which reappear by preference in the dream are those of which we have thought most distractedly. What is there astonishing about that? The ego of the dream is an ego that is relaxed; the memories which it gathers most readily are the memories of relaxation and distraction, those which do not bear the mark of effort.
It is true that in very profound slumber the law that regulates the reappearance of memories may be very different. We know almost nothing of this profound slumber. ”

“ But let us hasten to say that sounds do not play in our dreams so important a rôle as colors. Our dreams are, above all, visual, and even more visual than we think. To whom has it not happened—as M. Max Simon has remarked—to talk in a dream with a certain person, to dream a whole conversation, and then, all of a sudden, a singular phenomenon strikes the attention of the dreamer. ”

“ According to the Freudians a dream always means something, but never what it appears to mean. It is symbolic and expresses desires or fears which we refuse ordinarily to admit to consciousness, either because they are painful or because they are repugnant to our moral nature. A watchman is stationed at the gate of consciousness to keep them back, but sometimes these unwelcome intruders slip past him in disguise. ”

“ He would avoid the absurdity if he would remain a simple spectator of the procession of images which compose his dream. But when he strongly desires to explain it, his explanation, intended to bind together incoherent images, can be nothing more than a bizarre reasoning which verges upon absurdity. I recognize, indeed, that our superior intellectual faculties are relaxed in sleep, that generally the logic of a dreamer is feeble enough and often resembles a mere parody of logic. But one might say as much of all of our faculties during sleep. ”

“ Yes, I believe indeed that all our past life is there, preserved even to the most infinitesimal details, and that we forget nothing, and that all that we have felt, perceived, thought, willed, from the first awakening of our consciousness, survives indestructibly. But the memories which are preserved in these obscure depths are there in the state of [Pg 34] invisible phantoms. They aspire, perhaps, to the light, but they do not even try to rise to it; they know that it is impossible and that I, as a living and acting being, have something else to do than to occupy myself with them. ”

“ This choice which you continually accomplish, this adaptation, ceaselessly renewed, is the first and most essential condition of what is called common sense. But all this keeps you in a state of uninterrupted tension. You do not feel it at the moment, any more than you feel the pressure of the atmosphere, but it fatigues you in the long run. Common sense is very fatiguing. ”

“ To speak only of those that play the principal rôle, the changing colors and forms, which deploy before us when our eyes are closed, never have well-defined contours. Here are black lines upon a white background. They may represent to the dreamer the page of a book, or the facade of a new house with dark blinds, or any number of other things. Who will choose? What is the form that will imprint its decision upon the indecision of this material? This form is our memory.
Let us note first that the dream in general creates nothing. ”

“ The incoherence of the dream seems to me easy enough to explain. As it is characteristic of the dream not to demand a complete adjustment between the memory image and the sensation, but, on the contrary, to allow some play between them, very different memories can suit the same sensation. ”

“ The brain, then, is that which allows the mind to adjust itself exactly to circumstances. It is the organ of attention to life. Should it become deranged, however slightly, the mind is no longer fitted to the circumstances ”

“ We cannot say, then, that it is a dream. In sleep, properly speaking, in sleep which absorbs our whole personality, it is memories and only memories which weave the web of our dreams. But often we do not recognize them. They may be very old memories, forgotten during waking hours, drawn from the most obscure depths of our past; they may be, often are, memories of objects that we have perceived distractedly, almost unconsciously, while awake. ”

“ You will see that at a certain time in his life Stevenson had come to be in an habitual psychical state where it was very hard for him to say whether he was sleeping or waking. That appears to me to be the truth. When the mind creates, I would say when it is capable of giving the effort of organization and synthesis which is necessary to triumph over a certain difficulty, to solve a problem, to produce a living work of the imagination, we are not really asleep, or at least that [Pg 31] part of ourselves which labors is not the same as that which sleeps. ”

“ Still considering the sensation of sight, we ought to add to these visual sensations which we may call internal all those which continue to come to us from an external source. The eyes, when closed, still distinguish light from shade, and even, to a certain extent, different lights from one another. These sensations of light, emanating from without, are at the bottom of many of our dreams. A candle abruptly lighted in the room will, for example, suggest to the sleeper, if his slumber is not too deep, a dream dominated by the image of fire, the idea of a burning building. ”

“ He drives the lightning through the air and with the product feeds his crops. He makes the desert to blossom as the rose and out of the sea he draws forth dry land. He treats the earth as his habitation, remodeling it in accordance with his ever-varying needs and increasing ambitions. ”

“ Some say that sleep consists in isolating oneself from the external world, in closing the senses to outside things. But we have shown that our senses continue to act during sleep, that they provide us with the outline, or at least the point of departure, of most of our dreams. Some say: "To [Pg 44] go to sleep is to stop the action of the superior faculties of the mind," and they talk of a kind of momentary paralysis of the higher centers. I do not think that this is much more exact. In a dream we become no doubt indifferent to logic, but not incapable of logic. ”

“ In the hands of fanatical Freudians this theory has developed the wildest extravagancies, and the voluminous literature of psycho-analysis contains much that seems to the layman quite as absurd as the stuff which fills the twenty-five cent dream book.
It is impossible to believe that the subconsciousness of every one of us contains nothing but the foul and monstrous specimens which they dredge up from the mental depths of their neuropathic patients and exhibit with such pride. ”

“ The phenomenon is easily enough [Pg 23] explained. It is in general necessary for us to hear sounds in a dream. From nothing we can make nothing. And when we are not provided with sonorous material, a dream would find it hard to manufacture sonority.
There is much more to say about the sensations of touch than about those of hearing, but I must hasten. We could talk for hours about the singular phenomena which result from the confused sensations of touch during sleep. These sensations, mingling with the images which occupy our visual field, modify them or arrange them in their own way. ”

“ When in the Palace of Night scene of his fairy play, the redoubtable Tyltyl unlocks the cage where are confined the nightmares and all other evil imaginings, he shuts the door in time to keep them in and then opens another revealing a lovely garden full of blue birds, which, though they fade and die when brought into the light of common day, yet encourage him to continue his search for the Blue Bird that never fades, but lives everlastingly. ”

“ One cannot imagine the degree of sharpness, of acuity, which may be obtained during sleep by these interior sensations. They doubtless already exist as well during waking. But we are then distracted by practical action. We live outside of ourselves. But sleep makes us retire into ourselves. It happens frequently [Pg 27] that persons subject to laryngitis, amygdalitis, etc., dream that they are attacked by their affection and experience a disagreeable tingling on the side of their throat. When awakened, they feel nothing more, and believe it an illusion ”

“ Dream books in all languages continued to sell in cheap editions and the interpreters of dreams made a decent or, at any rate, a comfortable living out of the poorer classes. But the psychologist rarely paid attention to dreams except incidentally in his study of imagery, association and the speed of thought. But now a change has come over the spirit of the times. The subject of the significance of dreams, so long ignored, has suddenly become a matter of energetic study and of fiery controversy the world over. ”

“ It is the state into which you naturally fall when you let yourself go, when you no longer have the power to concentrate yourself upon a single point, when you have ceased to will. What needs much more to be explained is the marvelous mechanism by which at any moment your will obtains instantly, and almost unconsciously, the concentration of all that you have within you upon one and the same point, the point that interests you. But to explain this is the task of normal psychology, of the psychology of waking, for willing and waking are one and the same thing. ”
