Okay, so, just a really quick theory today. Maybe the temple isn't just a place of heeling or what ever. Maybe its a temporal temple. Where the "others" can go in, and take someone to a certain point in their previous history. So in a way, the temple is exempt from time itself. This theory would explain why Ben didn't remember going into the temple and getting shot and such. Because his physical body had been taken back to before he was shot.
And this isn't actually part of the theory its just somthing i thought might be interesting. But maybe the monster is in fact an accumulation of all the lost time.
