The Secret Life of Time
Some nights—more than I like, lately—I wake to the sound of the bedside clock. The room is dark, without detail, and it expands in such a way that it seems as if I’m outdoors, under an empty sky, or underground, in a cavern. I might be falling through space. I might be dreaming. I could be dead. Only the clock moves, its tick steady, unhurried. At these moments I have the most chilling understanding that time moves in only one direction.
