P和T分别代表了16和20，牌坊中的P和F代表了16和6，估计很多人通过这些数字的含义找到了其中的规律，寂静岭PT是一款未完成的游戏，游戏的场景则是一个循环的L，之前寂静岭4房间的21圣礼，在PT里面可以在L中找到12这个数字，同时“神”留给我了一段话：
I walked. I could do nothing but walk. And then, I saw me, walking in front of myself. But, it wasn’t really me. Watch out. The gap in the door… it’s a separate reality. The only me is me. Are you sure the only you is you?
