Rachel went to bed; she lay in the dark, it seemed to her, for a very long time, but at length, waking from a transparent kind of sleep, she saw the windows white in front of her, and recollected that some time before she had gone to bed with a headache, and that Helen had said it would be gone when she woke. She supposed, therefore, that she was now quite well again. At the same time the wall of her room was painfully white, and curved slightly, instead of being straight and flat. Turning her eyes to the window, she was not reassured by what she saw there. The movement of the blind as it filled with air and blew slowly out, drawing the cord with a little trailing sound along the floor, seemed to her terrifying, as if it were the movement of an animal in the room.
