"I am a good sleeper, and I do not remember ever waking of my own accord in the middle of my sleep. One night, about 2 or 3 o'clock, I was abruptly awoke. With my eyes still shut I thought, 'This is one of B.'s tricks. What is she going to make me see?' I then looked at the opposite wall; I saw a circular luminous spot, and in the centre a brilliant object, about the size of a melon, that I stared at for several seconds, being wide awake, before it disappeared. I could not distinguish any form clearly, nor any detail, but the object was round, and parts of it appeared to be less luminous. I imagined that she had wished to show me a skull, but I could not recognise it; the wall was lighted up in that place as if by a strong lamp; the room was not completely dark, because the window had outside blinds, and the curtains were drawn back; but this brilliant object did not seem to give out any light beyond the area of which it occupied the centre on the wall. That was all. I waited a moment without seeing anything else, then I went fast asleep again. The next day I found Bertha, who had come to visit the hospital, and I questioned her cautiously. She had tried to show me first of all some dogs round my bed, then some men quarrelling, and finally a lantern. That was all. It will be seen that though the first two attempts failed, the third succeeded perfectly. "After that, Bertha very often tried to hallucinate me; but I have never either seen or heard anything. "I was more sensible to transmissions of a vague and general character. I have written elsewhere of illusions of the sense of space: I had a complete illusion of this kind, and P. a very curious commencement of an hallucination. I have also described the causeless terror that Bertha could inspire. "Here is another account of a fright. One evening I was entering my house, at midnight. On the landing, as I was putting my hand on the door-handle, I said to myself, 'What a nuisance! here is another of B.'s tricks! She is going to make me see something terrifying in the passage; it is very disagreeable.' I was really a bit nervous. I opened the door suddenly, with my eyes shut, and seized a match; in a few minutes I was in bed, and, blowing out my candle, I put my head under the bed-clothes, like a child. The next day Bertha asked me if I had not seen a skeleton in the passage or in my room, and been very much frightened. It need hardly be said that a skeleton was the last thing in the world that could frighten me; and frankly, I think that I am not more of a coward than the common run of men." On another occasion Dr. Gibotteau was in the company of a friend, M. P. They had just parted from Bertha.
