The morning to them is the shadow of death;
They are familiar with the dark terrors of midnight.
Besides this fact that the night befriends and masks every treacherous foe, it is also to be remembered that man is weakest at night. Not only is he weaker than by day in the veil drawn over his senses, but physiologically also. When the body is wearied out by the toils or combats of the day, and the mind haunted by dreams of danger, there are present all the terrors which Byron portrays around the restless pillow of Sardanapalus. The war-horse of the day becomes a night-mare in the darkness. In the Heimskringla it is recorded: ‘Vanland, Svegdir’s son, succeeded his father and ruled over the Upsal domain. He was a great warrior, and went far around in different lands. Once he took up his winter abode in Finland with Snio the Old, and got his daughter Drisa in marriage; but in spring he set out leaving Drisa behind, and although he had promised to return within three years he did not come back for ten. Then Drisa sent a message to the witch Hulda; and sent Visbur, her son by Vanland, to Sweden. Drisa bribed the witch-wife Hulda, either that she should bewitch Vanland to return to Finland or kill him. When this witch-work was going on Vanland was at Upsal, and a great desire came over him to go to Finland, but his friends and counsellors advised him against it, and said the witchcraft of the Fin people showed itself in this desire of his to go there. He then became very drowsy, and laid himself down to sleep; but when he had slept but a little while he cried out, saying, ‘Mara was treading on him.’ His men hastened to help him; but when they took hold of his head she trod on his legs, and when they laid hold of his legs she pressed upon his head; and it was his death.’[5]
This witch is, no doubt, Hildur, a Walkyr of the Edda, leading heroes to Walhalla. Indeed, in Westphalia, nightmare is called Walriderske. It is a curious fact that ‘Mara’ should be preserved in the French word for nightmare, Cauche-mar, ‘cauche’ being from Latin calcare, to tread. Through Teutonic folklore this Night-demon of many names, having floated from England in a sieve paddled with cow-ribs, rides to the distress of an increasingly unheroic part of the population. Nearly always still the ‘Mahrt’ is said to be a pretty woman,—sometimes, indeed, a sweetheart is involuntarily transformed to one,—every rustic settlement abounding with tales of how the demoness has been captured by stopping the keyhole, calling the ridden sleeper by his baptismal name, and making the sign of the cross; by such process the wicked beauty appears in human form, and is apt to marry the sleeper, with usually evil results. The fondness of cats for getting on the breasts of sleepers, or near their breath, for warmth, has made that animal a common form of the ‘Mahrt.’ Sometimes it is a black fly with red ring around its neck. This demoness is believed to suffer more pain than it inflicts, and vainly endeavours to destroy herself.
In savage and nomadic times sound sleep being an element of danger, the security which required men to sleep on their arms demanded also that they should sleep as it were with one eye open. Thus there might have arisen both the intense vividness which demons acquired by blending subjective and objective impressions, and the curious inability, so frequent among barbarians and not unknown among the men civilised, to distinguish dream from fact. The habit of day-dreaming seems, indeed, more general than is usually supposed. Dreams haunt all the region of our intellectual twilight,—the borderland of mystery, where rise the sources of the occult and the mystical which environ our lives. The daily terrors of barbarous life avail to haunt the nerves of civilised people, now many generations after they have passed away, with special and irrational shudders at certain objects or noises: how then must they have haunted the dreams of humanity when, like the daughter of Nathan the Wise, rescued from flames, it passed the intervals of strife
With nerves unstrung through fear,
And fire and flame in all she sees or fancies;
Her soul awake in sleep, asleep when wide awake?
Among the sources of demoniac beliefs few indeed are more prolific than Dreams. ‘The witchcraft of sleep,’ says Emerson, ‘divides with truth the empire of our lives. This soft enchantress visits two children lying locked in each other’s arms, and carries them asunder by wide spans of land and sea, wide intervals of time. ‘Tis superfluous to think of the dreams of multitudes; the astonishment remains that one should dream; that we should resign so quietly this deifying reason and become the theatre of delusions, shows, wherein time, space, persons, cities, animals, should dance before us in merry and mad confusion, a delicate creation outdoing the prime and flower of actual nature, antic comedy alternating with horrid spectres. Or we seem busied for hours and days in peregrinations over seas and lands, in earnest dialogues, strenuous actions for nothings and absurdities, cheated by spectral jokes, and waking suddenly with ghostly laughter, to be rebuked by the cold lonely silent midnight, and to rake with confusion in memory among the gibbering nonsense to find the motive of this contemptible cachinnation.’[6]
It has always been the worst of periods of religious excitement that they shape the dreams of old and young, and find there a fearful and distorted, but vivid and realistic, embodiment of their feverish experiences. In the days of witchcraft thousands visited the Witches’ Sabbaths, as they believed and danced in the Walpurgis orgies, borne (by hereditary orthodox canon) on their own brooms up their own chimneys; and to-day, by the same morbid imaginations, the victims are able to see themselves or others elongated, levitated, floating through the air. If people only knew how few are ever really wide-awake, these spiritual nightmares would soon reach their termination. The natural terrors before which helpless man once cowered, have been prolonged past all his real victories over his demons by a succession of such nightmares, so that the vulgar religion might be portrayed somewhat as Richard Wagner described his first tragedy, in which, having killed off forty-two of his characters, he had to bring them back as ghosts to carry on the fifth act!
