Ludwig Laistner, however, appears to have been the first to argue in detail that dreams, and especially nightmares, have played an important part in the evolution of mythological ideas. 'If we bear in mind,' he said in the Preface to his great work, 'how intimately poetry and religion are connected with myth, we encounter the surprising fact that the first germ of these highly important vital manifestations is not to be found in any action of the waking mind, but in sleep, and that the chief and oldest teacher of productive imagination is not to be found in the experiences of life, but in the phantasies of dream.'[257] The pictures men formed of the over-world and the under-world have the character of dreams and hypnagogic visions, and this is true even within the sphere of Christianity.[258] The invention of Hell, Maudsley has declared, would find an adequate explanation, if such is needed, in the sufferings of some delirious patients, while the apocalyptic vision of Heaven with which our Christian Bible concludes, is, Beaunis remarks, nothing but a long dream.[259] And if it is true, as Baudelaire has said, that 'every well conformed brain carries within it two infinites: Heaven and Hell,' we may well believe that both Heaven and Hell find their most vivid symbolism in the spontaneous action of dreams.
In migraine and the epileptic aura visions of diminutive creatures sometimes occur, and occasionally micropsic vision in which real objects appear diminished. It has been suggested by Sir Lauder Brunton that we may here have the origin of fairies, at all events for some races of fairies; for fairies, though diminutive in some countries, as in England, are not diminutive in others, as in Ireland. A more normal and frequent channel of intercourse with such creatures is, however, to be found in dreams. This is illustrated by the following dream experienced by a lady: 'I saw a man wheeling along a cripple. Eventually the cripple became reduced to about the size of a walnut, and the man told me that he had the power of becoming any size and of going anywhere. To my horror he then threw him into the water. In answer to my remonstrances that he would surely be drowned, the man said that it was all right, the little fellow would be home in a few hours. He then shouted out, "What time do you expect to get back?" The tiny creature, who was paddling along in the water, then took out a miniature watch, and replied: "About seven!"'[260] In a dream of my own I saw little creatures, a few inches high, moving about and acting on a diminutive stage. Though I regarded them as really living creatures, and not marionettes, the spectacle caused me no surprise.
The dream-like character of myths, legends, and fairy tales is probably, however, not entirely due to direct borrowing from the actual dreams of sleep, or even from the hallucinations connected with insanity, music, or drugs, though all these may have played their part. The greater nearness of the primitive mind to the dream-state involves more than a tendency to embody in waking life conceptions obtained from dreams. It means that the waking psychic life itself is capable of acting in a way resembling that of the sleeping psychic life, and of evolving conceptions similar to dreams.
This point of view has in recent years been especially set forth by Freud and his school, who argue that the laws of the formation of myths and fairy tales are identical with the laws in accordance with which dreams are formed.[261] It certainly seems to be true that the resemblances between dreams and legends are not adequately explained by supposing that the latter are moulded out of the former. We have to believe that on the myth-making plane of thought we are really on a plane that is more nearly parallel with that of dreaming than is our ordinary civilised thought. We are in a world of things that are supernormally enormous or delicate, and the emotional vibrations vastly enlarged, a world in which miracles happen on every hand and cause us no surprise. Slaughter and destruction take place on the heroic scale with a minimum expenditure of effort; men are transformed into beasts and beasts into men, so that men and beasts converse with each other.[262]
Finally, it may be observed that the atmosphere into which genius leads us, and indeed all art, is the atmosphere of the world of dreams. The man of genius, it is often said, has the child within him; he is, according to the ancient dictum, which is still accepted, not without an admixture of insanity, and he is unquestionably related to the primitive myth-maker. All these characteristics, as we see, bring him near to the sphere of dreaming, and we may say that the man of genius is in closer touch with the laws of the dream world than is the ordinary civilised man. 'It would be no great paradox,' remarks Maudsley, 'to say that the creative work of genius was excellent dreaming, and dramatic dreaming distracted genius.'[263] This has often been recognised by some of the most typical men of genius. Charles Lamb, in speaking of Spenser, referred to the analogy between dreaming and imagination. Coleridge, one of the most essential of imaginative men, argued that the laws of drama and of dreaming are the same.[264] Nietzsche, more recently, has developed the affinity of dreaming to art, and in his Birth of Tragedy argued that the Appollonian or dream-like element is one of the two constituents of tragedy. Mallarmé further believed that symbolism, which we have seen to be fundamental in dreaming, is of the essence of art. 'To name an object,' he said, 'is to suppress three-quarters of the enjoyment in a poem which is made up of the happiness of gradually divining; to suggest—that is our dream. The perfect usage of this mystery constitutes symbolism: to evoke an object, little by little, in order to exhibit a state of the soul, or, inversely, to choose an object, and to disengage from it a state of the soul by a series of decipherments.'[265] It may be added that imaginative and artistic men have always been prone to day-dreaming and reverie, allowing their fancies to wander uncontrolled, and in so doing they have found profit to their work.[266] From Socrates onwards, too, men of genius have sometimes been liable to fall into states of trance, or waking dream, in which their mission or their vision has become more clearly manifested;[267] the hallucinatory voices which have determined the vocation of many great teachers belong to psychic states allied to these trances.
It is scarcely necessary to refer to the occasional creative activity of men of genius during actual sleep or to the debts which they have acknowledged to suggestions received in dreams.[268] This has perhaps, indeed, been more often exaggerated than overlooked. There can be no doubt that a great many writers and thinkers, including some of the highest eminence, have sometimes been indebted to their dreams. We might expect as much, for most people occasionally have more or less vivid or suggestive new ideas in dreams,[269] and it is natural that this should occur more often, and to a higher degree, in persons of unusual intellectual force and activity. But it is more doubtful whether the creative activity of normal dreams ever reaches a sufficient perfection to take, as it stands, a very high place in a master's work. Coleridge's 'Kubla Khan' has the most notable claim to be an exception to this rule. This poem was written by Coleridge in 1788, soon after 'Christabel,' and at a time when the poet was suffering much from depression, and taking a great deal of laudanum. We are entitled to assume, therefore, that the poem was composed under the influence of opium, and not in normal sleep. It may be added that it is difficult to believe that Coleridge could have recalled the whole poem from either a normal or abnormal dream; as a rule, when we compose verses in sleep we can usually recall only the last two, or at most four, lines.[270] Moreover, there is reason to believe that the first draft of 'Kubla Khan' was not the poem as we now know it.[271]
After Coleridge's 'Kubla Khan' the most important artistic composition usually assigned to a dream is the Trillo del Diavolo sonata of Tartini, the eighteenth-century composer and violinist, who has been called the prototype of Paganini. Tartini, who was a man of nervous and emotional temperament, seems to have possessed real genius, and this sonata is his principal work. But there is not the slightest ground for stating that it was composed in a dream, and Tartini himself made no such claim.[272]
The imaginative reality of dreams is perhaps appreciated by none so much as by those who are deprived of some of their external senses. Thus a deaf and dumb writer of ability who has precise and highly emotional dreams—which sometimes remind him of the atmosphere of Poe's tales, and are occasionally in organised sequence from night to night—writes: 'The enormous reality and vividness of these dreams is their remarkable point. They leave a mark behind. When I come to consider I believe that much that I have written, and many things that I have said and thought and believed, are directly due to these dream-experiences and my ponderings over how they came. Beneath the superficiality of our conscious mind—prim, smug, self-satisfied, owlishly wise—there lies the vast gulf of a subconscious personality that is dark and obscure, seldom seen or even suspected. It is this, I think, that wells up into my dreams. It is always there—always affecting us and modifying us, and bringing about strange and unforeseen new things in us—but in these dreams I peer over the edge of the conscious world into the giant-house and Utgard of the subconscious, lit by one ray of sunset that shows the weltering deeps of it. And the vivid sense of this is responsible for many things in my life.'[273]
