When those best acquainted with the slender and melancholy Félida N., or the ordinary, quiet, well-behaved Louis V.; the industrious and respected evangelist Ansel Bourne, or the large-brained, intellectual leader of women, Alma Z., saw them in their ordinary state, before any subliminal personality had emerged and made itself known, no one of those most intimate acquaintances, no expert in character-reading, no student of mental science could have given any reasonable intimation that any one of them would develop a second personality, much less give any trustworthy opinion as to the character which the new personality would possess.
A few months ago I was called in haste to see a patient, a large, strong man of one hundred and eighty pounds weight, who had been thrown down and trampled upon by his nineteen-year-old son during an attack of somnambulism, and had received such serious injuries as to require immediate surgical aid. The next day this son came to consult me regarding his unfortunate habit of sleep-walking, which has often got him into trouble before, and has now resulted in serious injury to his father. He is a slight youth of one hundred and twenty pounds weight, light hair, gray eyes, and a bright, frank face, expressive of good health and good nature--"a perfect gentleman," as his father expressed it, "when himself, but ten men cannot manage him when he gets up in his sleep; he will do what he sets out to do."
Who would ever imagine that this slender, good-natured, gentlemanly lad, sooner than any other lad, would in his sleep develop somnambulism and a second personality, or that when it came that second personality should prove a stubborn Samson?
Little could Prof. Janet imagine that beneath the surface consciousness of that serene and stupid Léonie dwelt the frisky, vivacious, fun-loving Léontine, waiting only the magic key of hypnotism to unlock and bring her to the surface to reign instead of the heavy Léonie.
The people who, in various ways, develop second personalities may not differ, it seems, in any perceptible manner from other people; is it not quite possible, then, that other normal, ordinary people, possess a second personality, deep-down beneath their ordinary, everyday self, and that under conditions which favor a readjustment, this hidden subliminal self may emerge and become for a longer or a shorter time the conscious, acting one; and not only so, but may prove to be the brighter and better organized of the two?
