As I walk back to my room, I pass room 201. I don’t know what it is, but every time I walk by this room, I get the chills. The door is closed, and there is a “DO NOT DISTURB” sign hanging from the door knob, even though the room is empty. I press my ear against the door. It’s silent inside. I reach out my hand and brush my fingers against the door. On an impulse, I lower my hand onto the door knob. And I try to turn it.
