This is a lavishly decorated wedding hall. You had come here to attend the wedding ceremony of your friend. You went in one of the rooms in the hall to take a nap. Later when you came out from the room you found out that you were the only person inside the hall. Everyone has left and the main exit from the hall is locked. This means you are trapped inside the hall and that is very embarrassing. It will be even more embarrassing if someone finds you locked inside the hall. You should think very smartly and look for a way to escape from the hall as fast as you can.
