An early analysis of the effect of dreams on our sub/unconsciousness. Excerpt below:
The subject which I have to discuss here is so complex, it raises so many questions of all kinds, difficult, obscure, some psychological, others physiological and metaphysical; in order to be treated in a complete manner it requires such a long development—and we have so little space, that I shall ask your permission to dispense with all preamble, to set aside unessentials, and to go at once to the heart of the question.
A dream is this. I perceive objects and there is nothing there. I see men; I seem to speak to them and I hear what they answer; there is no one there and I have not spoken. It is all as if real things and real persons were there, then on waking all has disappeared, both persons and things. How does this happen?
But, first, is it true that there is nothing there? I mean, is there not presented a[Pg 16] certain sense material to our eyes, to our ears, to our touch, etc., during sleep as well as during waking?
Close the eyes and look attentively at what goes on in the field of our vision. Many persons questioned on this point would say that nothing goes on, that they see nothing. No wonder at this, for a certain amount of practise is necessary to be able to observe oneself satisfactorily. But just give the requisite effort of attention, and you will distinguish, little by little, many things. First, in general, a black background. Upon this black background occasionally brilliant points which come and go, rising and descending, slowly and sedately. More often, spots of many colors, sometimes very dull, sometimes, on the contrary, with certain people, so brilliant that reality cannot compare with it. These spots spread and shrink, changing form and color, constantly displacing one another. Sometimes the change is slow and gradual, sometimes again it is a whirlwind of vertiginous rapidity. Whence comes all this phantasmagoria? The physiologists and[Pg 17] the psychologists have studied this play of colors. “Ocular spectra,” “colored spots,” “phosphenes,” such are the names that they have given to the phenomenon. They explain it either by the slight modifications which occur ceaselessly in the retinal circulation, or by the pressure that the closed lid exerts upon the eyeball, causing a mechanical excitation of the optic nerve. But the explanation of the phenomenon and the name that is given to it matters little. It occurs universally and it constitutes—I may say at once—the principal material of which we shape our dreams, “such stuff as dreams are made on.”
Thirty or forty years ago, M. Alfred Maury and, about the same time, M. d’Hervey, of St. Denis, had observed that at the moment of falling asleep these colored spots and moving forms consolidate, fix themselves, take on definite outlines, the outlines of the objects and of the persons which people our dreams. But this is an observation to be accepted with caution, since it emanates from psychologists already half asleep. More recently an[Pg 18] American psychologist, Professor Ladd, of Yale, has devised a more rigorous method, but of difficult application, because it requires a sort of training. It consists in acquiring the habit on awakening in the morning of keeping the eyes closed and retaining for some minutes the dream that is fading from the field of vision and soon would doubtless have faded from that of memory. Then one sees the figures and objects of the dream melt away little by little into phosphenes, identifying themselves with the colored spots that the eye really perceives when the lids are closed. One reads, for example, a newspaper; that is the dream. One awakens and there remains of the newspaper, whose definite outlines are erased, only a white spot with black marks here and there; that is the reality. Or our dream takes us upon the open sea—round about us the ocean spreads its waves of yellowish gray with here and there a crown of white foam. On awakening, it is all lost in a great spot, half yellow and half gray, sown with brilliant points. The spot was there, the brill[Pg 19]iant points were there. There was really presented to our perceptions, in sleep, a visual dust, and it was this dust which served for the fabrication of our dreams.
