Several cases of sleep drunkenness have come under my own notice.
A gentleman was roused one night by his wife, who heard the street-door bell ring. He got up, and, without paying attention to what she said, dragged the sheets off of the bed, tore them hurriedly into strips, and proceeded to tie the pieces together. She finally succeeded in bringing him to himself, when he said he thought the house was on fire, and he was providing means for their escape. He did not recollect having had any dream of the kind, but was under the impression that the idea had occurred to him at the instant of his awaking.
Another was suddenly aroused from a sound sleep by the slamming of a window shutter by the wind. He sprang instantly from his bed, and, seizing a chair that was near, hurled it with all his strength against the window. The noise of the breaking of glass fully awakened him. He explained that he imagined some one was trying to get into the house and had let his pistol fall on the floor, thereby producing the noise which had startled him.
A lady informed me that upon one occasion she had gone to bed very tired, but was suddenly startled from her sleep by a voice calling her by name. Without stopping a moment, she arose, put on her shoes and stockings, lit a candle, took a loaded pistol from a shelf near her husband’s head, cocked it, and was leaving the room, the pistol in one hand and the candle in the other, when she was seized by her husband. She turned, recognized him at once, and would have fallen to the floor had he not caught her in his arms. Her husband, who slept in the same bed with her, had heard one of the children cry in an adjoining room, and had called her. She, hearing his voice, had partially awakened, but had conceived the idea that he had called to her from another part of the house, where some danger menaced him. She had acted upon this supposition, and was perfectly conscious of every movement she had made.
It does not appear that some persons are more liable to attacks of sleep drunkenness than others. Neither do I know of any means by which its occurrence could be prevented. It is a natural phenomenon, to which all are liable. It is more important in its medico-legal relations than any other.
