Unconsciousness discussion

This unusual castle is built entirely of white marble and gold, with almost unbelievable swirling turrets and pillars, marble statues of handsome heroes dotting the walls. Inside is about the same, with torches lighting the halls. However, one of the interesting things about this building is that all you have to do to get to a specific room is concentrate on it. This is an especially handy trick when you have to use the bathroom, but unfortunately everyone can use this same trick; meaning that people can potentially come into an occupied room - not so nice when you're using the facilities.
