This leads now to that which, according to folk belief, constitutes the very core, the chief ground for sleep walking and moon walking in a maiden. It is easy to understand the wish, on the part of the female sex with their strongly demanded sexual repression, to come to the beloved one and taste all the delights of satisfaction but without guilt. This is possible only through wandering in unconscious sleep. For, as my first patient explained, one is not accountable for anything that happens in this state, and thus can enjoy without sin and without consciousness of what is not permitted. Convention demands that the maiden wait until the lover approaches her, but in that unconscious state she may surrender herself. The need for repression explains then the subsequent amnesia. Yet wandering by night is not concerned merely with sexual enjoyment, over and above that it fulfills a second desire that arises out of childhood, as we know from psychoanalysis. Every small maiden has, that is, the wish to have a child by her father, her first love, which is often in later years defined thus, one might have a child, but without a husband. The night wandering fulfills this desire to have a child yet without sin. Therefore has that motive of an unconscious, not to say immaculate, conception inspired not a few poets, as it has already, as is well known, been active in the creation of the drama. Less transparent than that chief motive is the action of the light, sunlight as well as moonlight. The heroine of the story stands toward both in a special relationship. Her body is almost illuminated by its own light, her hair sparkles electrically when it is touched, "warm waves of light" emanate from her, which Soelver noticed at their first meeting, the sun seems expressly to seek her, a halo of impalpable beauty surrounds her and above all glows from the depths of her eyes. Not only so, Gro seems to dwell chiefly in the light, whose last drops she greedily absorbs within herself. When the light fades, her body becomes cold as ice like a corpse. In similar manner the shining of the full moon affects her, the light of which the stones of her gold cross have absorbed. The first time that the slumbering youth saw Gro wandering, it seemed to him as if the moonlight had been loosed from the planet and floated only in his room like a living being. The poet, to be sure, has offered no explanation of this mystical effect of light and what the reader may think for himself would be merely drawn from other sources. For this reason I will not pursue this point further.
