And thirdly, in some of these instances we see the man of genius achieving spontaneously, and unawares, much the same result as that which is achieved for the hypnotic subject by deliberate artifice. For he is in fact co-ordinating the waking and the sleeping phases of his existence. He is carrying into sleep the knowledge and the purpose of waking hours;--and he is carrying back into waking hours again the benefit of those profound assimilations which are the privilege of sleep. Hypnotic suggestion aims at co-operations of just this kind between the waking state in which the suggestion, say, of some functional change, is planned and the sleeping state in which that change is carried out,--with benefit persisting anew into waking life. The hypnotic trance, which is a _developed_ sleep, thus accomplishes for the ordinary man what ordinary sleep accomplishes for the man of genius. The coming chapters on Sleep and Hypnotism will illustrate this point more fully. But I may here anticipate my discussion of _dreams_ by quoting one instance where dreams, self-suggested by waking will, formed, as one may say, an integral element in distinguished genius. The late Robert Louis Stevenson, being in many ways a typical man of genius, was in no way more markedly gifted with that integrating faculty--that increased power over all strata of the personality--which I have ascribed to genius, than in his relation to his dreams (see "A Chapter on Dreams" in his volume _Across the Plains_). Seldom has the essential analogy between dreams and inspiration been exhibited in such a striking way. His dreams had always (he tells us) been of great vividness, and often of markedly _recurrent_ type. But the point of interest is that, when he began to write stories for publication, the "little people who managed man's internal theatre" understood the change as well as he. When he lay down to prepare himself for sleep, he no longer sought amusement, but printable and profitable tales; and after he had dozed off in his box-seat, his little people continued their evolutions with the same mercantile designs.... For the most part, whether awake or asleep, he is simply occupied--he or his little people--in consciously making stories for the market.... The more I think of it, the more I am moved to press upon the world my question: "Who are the Little People?" They are near connections of the dreamer's, beyond doubt; they share in his financial worries and have an eye to the bank book; they share plainly in his training; ... they have plainly learned like him to build the scheme of a considerate story and to arrange emotion in progressive order; only I think they have more talent; and one thing is beyond doubt,--they can tell him a story piece by piece, like a serial, and keep him all the while in ignorance of where they aim....
