So very little of the P.T. Demo is actually explained. From the weird baby foetus in the sink through to just why the same room keeps repeating over and over again, the demo does an excellent job of building tension without ever revealing anything about the game that was supposed to become Silent Hills. Perhaps the weirdest moment of all is when - after a few runs through the same corridor - the player eventually comes across a refrigerator hanging from the ceiling. Blood is gushing out of it and it just swings back and forth ominously. It's gone soon after, never to make another appearance. One can only wonder what horrors were contained within.
