sleep only at my periods of sleep walking, without crying out. All that I have described the Sister of Charity told me afterward. Naturally I did everything with closed eyes, without knowing it, and moved about as securely in the darkness as if it had been bright day. The next morning they told me about it and laughed over it." This is what she has to say of the influence of the light upon her sleep walking. "Here also Mother's coughing was the external cause as it had been when I was four years old. When Mother was ill, the lamp was left upon the window sill behind the curtain, burning brightly so that she would not be afraid. Now also, at the time of my first complicated sleep walking, such a light was burning behind the curtain throwing its light upon my bed and the wall. Mother had always left the light burning in order to see me at once, after I had sometimes climbed over the side of my crib at the age of four, when she was ill. The light however made me climb over to her, because in the dark no blood could be seen. Also when I began to moan, during my convulsive attacks, she made a light and came to my bed. Or she said, when my bed was pushed close to hers: 'Wait a moment; I will make a light and take you or you can climb over to me.' Next day I laughed with my parents over my visit at night, without suspecting that I would soon be repeating it actually in my sleep. And it was only for this, that I might, as at the very first time, enjoy the sight of Mother's blood. Now, when she had a light burning during her illness, this allured me in my sleep to climb out to her, as at that first time when she had made a light especially for me to climb over to her."
