There exists a better agreement of opinion over the relationship between sleep walking and the dream. Sleep walking, analogously to the latter, fulfills also wishes of the day, behind which stand always wishes from childhood. Only it must also be emphasized that the old, like the recent wishes, are exclusively or predominantly of a sexual nature. Because however that sexual desire is forbidden in the waking life, it must even as in the dream take refuge in the sleeping state, where it can be gratified unconsciously and therefore without guilt or punishment. Most of the sleep activities of our patient were performed originally in a state of apparent sleep, that is actually practiced in the conscious state until later they were carried out quite unconsciously. She would never then betray what when feigning sleep she had to conceal as causes. Finally the directly precipitating causes in her erotic nature for the sleep walking and moon walking seem especially to have been light and the shining of the moon, her puberty and her mother's sickness. All of our patient's sleep walking, in accordance with the etiology and interpretation, since it goes back to infantile sexuality, is half sexual, half outspokenly infantile. It reaches the greatest degree, indeed the moon walking sets in just at the time of sexual maturity and leads to the most complicated actions before the menses, that is at the time of the greatest sexual excitement. And this activity in sleep and the moon walking too almost cease when the patient enters upon regular sexual intercourse. The shining of every light stimulates her sexually, especially that of the moon. The wandering about in her nightgown or in the scantiest clothing is plainly erotically conditioned (exhibition), but also the going about in the ghostly hours (see later), finally the being wakened through the softest calling of her name by the mother, with whom alone she stands in a contact like that of hypnotic somnambulism.
