The naive egotism of superstition saw in the movements of the solar system only prognostications concerning its own bean crop, and could discern nothing in the dream-world but the efforts of the supernatural powers to communicate, in their usual shuffling and incompetent fashion, with man. The modern revolt from this childishness has swung the pendulum of interest in dreams so far up the other curve of the arc that there seems now to be a foolish fear of attaching any importance whatever to the strange experiences of sleep, and as a result an unscientific avoidance of the whole subject. The consequence of this absurd revulsion is that in a period of universal investigation one of the most curious functions of the brain is left unexamined and unexplained. Some dabbling there has been, with results of little more value than were the contents of the greasy, bethumbed dream-books of the eighteenth-century milkmaid or apprentice. The labour bestowed upon the matter has been mainly directed to efforts to prove the extreme rapidity with which dreams pass through the mind, and that it is some trivial outward cause at the very instant of awakening--such as a noise, a light, or a blow--which rouses the brain to this miraculous celerity of imaginative creation. The persistent assertion that a dream occurs only at the moment of awakening shows how little real attention has been given to the matter, since the most casual observation of "the dog that hunts in dreams" would have shown that he may be "chasing the wild deer and following the roe" in the grey Kingdom of Seeming without breaking his slumbers. He will start and twitch, and give tongue after the phantom quarry he dreams he is pursuing, and yet continue his sleep without an interval. But have it whichever way one likes, the heart of the mystery is not yet discovered. How do they explain why a noise or a gleam of light--such as the waking senses know familiarly--should at this magical moment of rousing cause the brain to create with inconceivable rapidity a crowd of phantasmagoria in order to explain to itself the familiar phenomena of light and sound? Dr. Friederich Scholz, in his recent volume upon "Sleep and Dreams," gives an example of rapid effort of the mind to explain the sensations felt by the sleeping body: "I dreamed of the Reign of Terror, saw scenes of blood and murder, appealed before the Revolutionary Tribunal, saw Robespierre, Marat, Fouquier-Tinville, all the personages of that time of horrors, argued with them, was finally, after a number of occurrences, condemned to death, was carried to the place of execution on a cart through enormous masses of people, was bound by the executioner to the board. The knife fell and I felt my head severed from my body. Thereupon I awoke and found that a loosened rod of the bed had fallen on my neck like the knife of the guillotine, and this had happened, my mother assured me, at the very moment when I awoke."...
