You have gone through a door that you weren't meant to go through and have stumbled into an old style adventure game.
You are in a small room decorated in dreadful taste. There is an open door in front of you. I'd take it if I were you. There is a chipped nightstand with peeling paint here. There is a book entitled "Find Billy" on the night stand. It might be a good read. There is a mirror on the wall. There is also an open trap door in the middle of the floor. You could go down but it doesn't look too inviting.
This room was last redecorated April 13, 1996.
