What happens when you’re stuck in a room with no windows, doors, or lights, but you can hear people outside talking?

The room is a cube. You are standing in the middle of the cube, and your back is against one of the walls. The walls of the cube are very sturdy. They feel cold. There is no windows. No doors. No lights. No ceiling. No floor. Just walls. It’s hard to tell, but the walls feel metallic. You can’t tell if there are any other rooms connected to this one, but you can hear people outside this room. You are not alone in the room with you, but you have no idea if anyone else is even in there with you. You can’t see them. You have no light to light the room. It’s pitch black.
