Should+he+open+his+eyes?

An uninvited guest, he thought. He shivered as he opened his eyes. Instead of seeing someone in particular, he saw a shadow on the wall where the plates had broken. A chill went up his spine. "Who are you?" He whispered, "What do you want from me?" The shadow disappeared. A ghost, he thought. The chandelier started to swing. Creak, creak, it went. He ran upstairs, his footsteps pounding on the stairs. He rushed into his room and slammed the door shut. He peeked outside his door. Someone, or something, had turned on the light in the room across from him.

Should he find out what's happening? or Should he wait in his room?
