We find first in the foreground a family disposition to sleep walking and moon influence. The brother significantly always wants in his wanderings to get into the sister's bed, while our patient herself openly plays the part of mother, especially the mother of the earliest childhood. It is interesting also that when in her married life she had to give up her pleasure in light and air, the disturbances of consciousness set in, from which she could free herself only through fixing her attention upon a point of light. She had the distinct feeling that from this point of light things would become clear to her. One can easily think of occasions of being dazed by sleep when perhaps the mother came with the candle in her hand to see whether her child was asleep and the child awoke. The whole remarkable occurrence would then be simply a desire for the mother's love, which she all her life long so sorely missed. Now for the last case, a twenty-three year old married woman suffering from a severe hysteria, who clung with great tenderness to her parents, but received a reciprocal love only from her father, while the mother preferred her sister. The patient told me of her moon walking: "I always wanted to sleep by the open blinds so that the moon could shine upon me. My oldest brother walked about in the night, drank water, went to the window and looked out, all of course in his sleep, then he went back to bed and slept on. At the same time he spoke very loudly, but quite unintelligible things and one could actually observe that the moon exercised an attraction over him. My younger healthy brother said that it was frightful, the many things that he uttered in the night. I also climbed out of bed one night when sixteen or seventeen years old, because I could not find the moon, and sought it and met my moon haunted brother. I immediately disappeared again going back to my bed and he did not see me.
