What are we to say to this distinction? I do not believe it is necessary to take it seriously, any more than the others. When is it that we pass judgment on the discontinuity and incoherence between our successive dreams? Not while we are dreaming them. When I am dreaming, I seem to be pursuing a life that has always been the same. I have no sort of an impression that the present dream has been preceded by different dreams having no connection with it. I have, on the contrary, exactly as I have when awake, the impression of an indefinite and single series of events, of an unrolling of them without arrest and without break. There is, therefore, on this point, no difference, but another resemblance between the dream and the reality, and the same impression of continuity and unity prevails in both. It is true that the aspect changes in waking, and our several dreams then appear detached from one another. But what of that? Are we sure that we shall not awake some day from what we now call the waking state, and find then that that state, continuous in appearance, was in reality composed of a series of separate, incoherent, and incongruous fragments?
Thus we are all the time coming upon the same illusion. We judge of the dream, not by what it is, but by what it seems to have been after we have waked. Instead of observing the impressions of the dreaming man while he is dreaming, we take notice of what he thinks about them after he has waked up. This is to falsify the comparison of the normal and dream life by regarding the normal life while we are in it, and the dream life when we have come out of it. The several other difficulties on which psychologists have insisted are capable of solution by the application of the same principle: the seeming suspension of the will; the want of correspondence of the moral standards of the dream with those of the waking condition; the confusion of temporal duration and sequence; and the transformations of personality and character, concerning which I would ask, however, if the eccentricities betrayed are not rather in the nature of more complete exposure. I have sometimes been surprised at the psychological revelations of dreams; faults and weaknesses that we do not avow when in the normal condition reveal themselves then with inexorable frankness; we yield to temptations that we evaded when awake, though inclined to them; to wickednesses which we kept closely shut up within us; reveal antipathies which we had dissimulated. Base desires break out, latent loves declare themselves, and things take place which, as in a play, bring the farthest depths of our hearts into the light; and when we wake we say: "That is true; it is just what I should have done under like circumstances. I had never thought of it, and I am not proud of it, but it is so."
There is this real distinction between the dream and the waking state: that when awake I know there is another condition, while in the dream I take no thought of the waking state. Awake, I know that I have been living the fantastic dream life, and have come out of it into a real life completely distinct from the other. I am in a first state, and know there is a second. But when I am dreaming I have no thought of another state that I have come out of and must return to; I do not feel that there is another existence, radically separated from this one; and I never compare the visions of my dreams with my waking world, for I know nothing of it. I have the impression of having always lived the life I am in, which seems natural; and even if I ask whether I am not dreaming, it is a merely verbal expression, with no accompanying sense of the meaning of it. Another distinction, and the only absolutely clear one, is that while we always wake from the dream, we never wake from the reality. This is why we believe in the reality and not in the dream.
These two differences are differences in degree, but they do not necessarily indicate differences in nature. Similar facts are frequent among hypnotics. We may plunge them into a condition of somnambulism which we will call a second state; and then, from that, magnetize them over again into another somnambulism, which we call the third state. Now the curious fact comes to pass that the subject in the third state recollects the second state, but when in the second state again, knows nothing of having been in the third state. "Lucie 3," says M. Pierre Janet, "recollected her normal life perfectly; she also recollected previous somnambulisms, and all that Lucie 2 had said.... It was a long and hard task to awaken this subject after she had passed a few minutes in the syncope already described. She then returned to ordinary somnambulism, but Lucie 2 could not tell me a word of what had happened to Lucie 3, and supposed she had been asleep and said nothing." Thus we have the same difference between two successive stages of somnambulism as between the dream and the waking state. But as the stages 2 and 3 are evidently of the same nature, so we have a right to suppose that the dream and the waking, whose phenomena as to each other are similar, are likewise of the same nature.
In the ordinary experience of mankind we do not awake from our normal condition; but is it proved that there is never any awakening, any third state into which we may pass? The supposition of some such state into which we pass by death is one of the fundamentals of nearly all religions; and in this sense we might contemplate the possibility of an awakening in which we shall be astonished at having given ourselves up go completely to the world of sense, at having taken a passing state for the definite one, an ephemeral world for the sole and absolute world, a provisional existence for the real one.
Even among men as we find them, we see some making an approach to a third state, if not living in it. What is science but the revelation of a new world, different from the visible one? When we see light and colors, they tell us of an invisible ether with particles vibrating with almost incalculable rapidity; when we hear faint or loud sounds, sharp or grave, they tell of the more or less ample and rapid vibrations of matter. When we perceive a multiple or varied reality, it shows us the single phenomenon of motion. These formulas do not, however, signify, as some mistake, that light, color, and sound do not exist, but that there is something else; and that if we could gain new senses, a new universe would open out to us. This means, simply, that the scientific man is already half waked up from his ordinary life, and has half entered a new world.
Metaphysics is a waking up of this kind. A metaphysician who really believes his doctrines, like Plato or Spinoza, is already living in a new world and contemplating the supposed reality in which we are still immersed as a matter of indifference away off in the dim twilight. To him, what we regard as reality is only appearance, while the eternal rain of atoms or the play of immaterial forces, or whatever he supposes the world to be made of, is the true reality.
Religion is another such awakening, and to the devout man this life is only a provisional one, a trial, the prelude to the true life; and while he may regard the world of sense as real too, he looks forward to the superior reality, which it is the privilege of the elect to contemplate; and it is some feeling of this kind that has sustained martyrs and has incited men of all ages and all faiths to suffer and endure, and die for what they believe.—Translated for the Popular Science Monthly from the Revue des Deux Mondes.
