One point of view I will first set forth. Two questions appear to me to stand out among those closely bound with our theme. First on the motor side. Why does not the sleep walker, who is enjoying apparently a specially deep slumber, sleep on quietly and work out the complexes of his unconscious somehow in a dream, even though with speech or movement there? Why instead is he urged forth and driven to wander about and engage in all sorts of complicated acts? It is one of the most important functions of the dream to prolong sleep quietly. And then in the second place, What value and significance must be attributed to the moon and its light? These two chief questions must be answered by any theory that would do justice to the question of sleep walking and moon walking.
PART I
Medical
Case I. Some years ago I treated a hysterical patient, exceedingly erotic. She was at that time twenty-two years old, and on her father's as well as on the mother's side, from a very degenerate family. Alcoholism and epilepsy could be traced with certainty to the third ascendant on both sides. The father's sister is mentally diseased, the patient's mother was an enuretic in her earlier years and a sleep walker. This mother, like her father when he was drunk, was markedly cruel and given to blows, characteristics, which according to our patient, sometimes almost deprived her of her senses and in her anger bordered upon frenzy.
The patient herself had been as the youngest child the spoiled darling of both parents and until her seventh year had been taken by them into their bed in the morning to play. In her first three years she always slept between the parents, preferably on the inner side of one of the two beds and with her legs spread, so that, in her mother's words: “One foot belongs to me and one to her father!” She was most strongly drawn, however, to the mother, toward whom at an early age she was sexually stimulated, already in her first year, if her statements can be relied upon, when she sat upon her mother's lap while nursing.
The little one early learned also that, when one is sick, one receives new playthings and especially much petting and tenderness, on account of which she often pretended to be sick purposely or she phantasied about dark forms and ugly faces, which of course she never saw, except to compel the mother to stay with her and show her special love and tenderness. Already in her second year she would go to bed most dutifully, “right gladly” to please father and mother and gain sexual pleasure thereby. The father then let her ride on his knee, stroked her upon her buttocks and kissed her passionately upon the lips. The desire after the mother became the stronger. When the latter had lain down and the little one had been good, then the child would creep to the mother under the feather bed and snuggle close to her body (“wind herself fast like a serpent”). The mother's firm body gave her extraordinary pleasure, yes, not infrequently it led to the expulsion of a secretion from the cervix uteri. (“The good comes,” as she expressed it.) I mention convulsive attacks and enuresis nocturna, as pathological affections of her childhood which belong to my theme. The patient had in fact suffered in her first year a concussion of the brain, through being thrown against a brick wall, with organic eclamptic attacks as a result. The great love which she had experienced because of this led her also later to imitate those attacks hysterically. In the fourth year, for example, when she had to sleep in a child's crib, no longer between the beloved parents, she immediately produced attacks of anxiety in which she saw ugly faces and witches as in the beginning of the eclamptic convulsions. Thereupon the frightened mother took her again into her own bed. Later also she often began to moan and fret until the mother would take her in her arms to ward off the threatened attacks, and thus she could stimulate herself to her heart's content. As she reports, at the height of the orgasm she expelled a secretion, her body began to writhe convulsively, her face became red as fire, her eyes rolled about and she almost lost herself in her great pleasure.
Concerning her enuresis, in its relation to urethral eroticism, the patient relates the following: “When I pressed myself against my mother's or brother's thigh, not only ‘the good’ came, but frequently also urine with it. At about eight years old there was often a very strong compulsion to urinate, especially at night, which would cause me to wet my bed. This was however according to my wish to pass not urine but that same secretion which I had voided at two or three years old, when I became so wildly excited with my mother, that is when, lying in bed with her, I pressed her thigh between mine. I could not stop it in spite of all threats or punishments. Very curiously I usually awoke when I voided urine, but I could not retain it in the face of the great pleasure.”
I lay emphasis upon a specially strong homosexual tendency[5] among her various perversions, although she had the usual sex relations with a legion of men with complete satisfaction. Furthermore, as sadistic-masochistic traits, there was an abnormal pleasure in giving and receiving blows and a passionate desire for blood. It was a sexual excitement that occurred when she saw her own blood or that of others. I have elsewhere[6] described this blood sadism and I will refer here to only two features, which are of significance also in regard to her moon walking. The first is her greatly exaggerated vaginal eroticism, which at menstruation especially was abnormally pleasurably excited. The second, on the other hand, was that our patient already at the age of two years should have experienced sexual pleasure in the mother's hemoptysis. Sitting on the mother's lap she stimulated herself upon the latter's breast, when she began to scrape and then to cough up blood. She reached after her bloody lips in order afterward to lick off her own fingers. As a result of the sexual overexcitement which occurred then, blood has afforded her enormous pleasure ever since, when she has looked upon it.
As for the rest of her life, I will refer to two other points only, which are not without importance for our problem. First of all was the change of dwelling after the father's death in our patient's seventh year. The other is her burning desire, arising in her third or fourth year, to play mother and most eagerly with a real live child. A baby doll, of which she came into possession, was only a substitute, although for want of something better she carried this around passionately and did not once lay it out of her arms while asleep. At the age of eight it was her greatest delight to trudge around with a small two year old girl from the house and sing her to sleep as her mother had once done to her. “Carrying that child around was my greatest delight until I was fourteen years old.”
I mentioned above that her mother had been sadistic and at the same time a sleep walker. “Mother herself told me that she also rather frequently walked at night. As a child she would wander around in her room without being able to find her bed again. Over and over again she would pass it without finding her way into it. Then she would begin to cry loudly with fright for her bed until Grandmother awoke and lifted her into bed. In the morning she remembered nothing at all about it.
