Am I just the same?’ She said, `When I am with you, you are quite pleasant, but when I am by myself, or have not seen you for some time, the picture I have of you changes in a remarkable way. Sometimes you seem quite idealized, and then again different.’ Here she hesitated, and I prompted her: `In what way different?’ Then she said, `Sometimes you seem rather dangerous, sinister, like an evil magician or a demon. I don’t know how I ever get such ideas — you are not a bit like that.'”
