Sleep comes fast, the way it does when you're too exhausted to fight it. But the dream doesn't let him rest. He opens his eyes, and he's standing in a hallway. It stretches out in front of him, long and straight, lit by fluorescent lights that buzz and flicker overhead. The walls are plain, the floor is plain, and the end of the hallway is just far enough away that he can't quite make it out. He starts walking toward it. But the end of the hallway doesn't get any closer. He walks faster. Still nothing. The lights above him flicker once, hard, and for a split second, everything goes dark.
