What one has meant to do during the day, as it turns out, sleep intervening, one accomplishes only in one’s dreams, that is to say after it has been distorted by sleep into following another line than one would have chosen when awake. The same story branches off and has a different ending. When all is said, the world in which we live when we are asleep is so different that people who have difficulty in going to sleep seek first of all to escape from the waking world. After having desperately, for hours on end, with shut eyes, revolved in their minds thoughts similar to those which they would have had with their eyes open, they take heart again on noticing that the last minute has been crawling under the weight of an argument in formal contradiction of the laws of thought, and their realisation of this, and the brief “absence” to which it points, indicate that the door is now open through which they will perhaps be able, presently, to escape from the perception of the real, to advance to a resting-place more or less remote on the other side, which will mean their having a more or less “good” night. But already a great stride has been made when we turn our back on the real, when we reach the cave in which “auto-suggestions” prepare—like witches—the hell-broth of imaginary maladies or of the recurrence of nervous disorders, and watch for the hour at which the storm that has been gathering during our unconscious sleep will break with sufficient force to make sleep cease. Not far thence is the secret garden in which grow like strange flowers the kinds of sleep, so different one from another, the sleep induced by datura, by the multiple extracts of ether, the sleep of belladonna, of opium, of valerian, flowers whose petals remain shut until the day when the predestined visitor shall come and, touching them, bid them open, and for long hours inhale the aroma of their peculiar dreams into a marvelling and bewildered being. At the end of the garden stands the convent with open windows through which we hear voices repeating the lessons learned before we went to sleep, which we shall know only at the moment of awakening; while, a presage of that moment, sounds the resonant tick of that inward alarum which our preoccupation has so effectively regulated that when our housekeeper comes in with the warning: “It is seven o’clock,” she will find us awake and ready. On the dim walls of that chamber which opens upon our dreams, within which toils without ceasing that oblivion of the sorrows of love whose task, interrupted and brought to nought at times by a nightmare big with reminiscence, is ever speedily resumed, hang, even after we are awake, the memories of our dreams, but so overshadowed that often we catch sight of them for the first time only in the broad light of the afternoon when the ray of a similar idea happens by chance to strike them; some of them brilliant and harmonious while we slept, but already
