It is in such characteristics as these--at once primitive, childlike, and insane--that we may find the charm of dreaming. In our sleeping emotional life we are much more like ourselves than we are in our sleeping intellectual life. It is a mistake to imagine that our moral and æsthetic instincts are abolished in dreams; they are often weakened, but by no means abolished. Such a result is natural when we remember that our emotions and instincts are both more primitive and less under the dominion of the external senses than are our ideas. Yet in both respects we are removed a stage backward in our dreams. The emotional intensity, the absurd logic, the tendency to personification--nearly all the points I have referred to as characterizing our dreams--are the characteristics of the child, the savage, and the madman. Time and space are annihilated, gravity is suspended, and we are joyfully borne up in the air, as it were, in the arms of angels; we are brought into a deeper communion with Nature, and in his dreams a man will listen to the arguments of his dog with as little surprise as Balaam heard the reproaches of his ass. The unexpected limitations of our dream world, the exclusion of so many elements which are present even unconsciously in waking life, imparts a splendid freedom and ease to the intellectual operations of the sleeping mind, and an extravagant romance, a poignant tragedy, to our emotions. "He has never known happiness," said Lamb, speaking out of his own experience, "who has never been mad." And there are many who taste in dreams a happiness they never know when awake. In the waking moments of our complex civilized life we are ever in a state of suspense which makes all great conclusions impossible; the multiplicity of the facts of life, always present to consciousness, restrains the free play of logic (except for that happy dreamer, the mathematician) and surrounds most of our pains and nearly all our pleasures with infinite qualifications; we are tied down to a sober tameness. In our dreams the fetters of civilization are loosened, and we know the fearful joy of freedom.
