It is "those twin-jailers of the daring" thought, Knowledge and Experience, that teach us surprise. We are surprised and incredulous when, in novels and plays, we come across good men and women, because Knowledge and Experience have taught us how rare and problematical is the existence of such people. In waking life, my friends and relations would, of course, have been surprised at hearing that I had committed a murder, and was, in consequence, about to be hanged, because Knowledge and Experience would have taught them that, in a country where the law is powerful and the police alert, the Christian citizen is usually pretty successful in withstanding the voice of temptation, prompting him to commit crime of an illegal character. But into Dreamland, Knowledge and Experience do not enter. They stay without, together with the dull, dead clay of which they form a part; while the freed brain, released from their narrowing tutelage, steals softly past the ebon gate, to wanton at its own sweet will among the mazy paths that wind through the garden of Persephone. Nothing that it meets with in that eternal land astonishes it because, unfettered by the dense conviction of our waking mind, that nought outside the ken of our own vision can in this universe be, all things to it are possible and even probable. In dreams, we fly and wonder not--except that we never flew before. We go naked, yet are not ashamed, though we mildly wonder what the police are about that they do not stop us. We converse with our dead, and think it was unkind that they did not come back to us before. In dreams, there happens that which human language cannot tell. In dreams, we see "the light that never was on sea or land," we hear the sounds that never yet were heard by waking ears. It is only in sleep that true imagination ever stirs within us. Awake, we never imagine anything; we merely alter, vary, or transpose. We give another twist to the kaleidoscope of the things we see around us, and obtain another pattern; but not one of us has ever added one tiniest piece of new glass to the toy.
