If, however, he ceased at that time to somnambulize, he was given to waking dreams, a sort of lethargy and abstraction that became habitual to him, and after the accès was over, his eyes flashed, his lips quivered, his voice was tremulous with emotion, a sort of ecstacy came over him, and he talked more like a spirit or an angel than a human being.

Physicians somnambulize their patients and extract teeth literally without pain.
