She lay in a dark room; shadows draped her still body. She listened to her own heavy breathing, deep and steady. She felt nothing, not the blankets beneath her, not the bed beneath her. She was not asleep; her vivid dreams were gone. She was not awake; her concious mind was not thinking. (< nice parallelism there) She was simply lying there. Lying between everything, night and day, light and darkness, sound and silence, and sleep and awareness.
