Slap him out of it
Yeah, probably on seperate levels then. That's one of the fascinating things about the series...
==> If he can't see or hear you, then there's not much you can do but follow him. Stay aware of your surroundings though; the monsters still might be able to get to him even if you can't interact with him.
Don't touch him, just keep an eye on him and follow him -- but also keep an eye out for that monster that was around.
Well damn, its like that one room in the church or Hotel. (Can't remember which.)
I that case watch him. Maybe he knows something we don't about the area/games.
try to pet his face .
> You might not be on the same 'level' of reality than him, just like before. Don't touch him, you don't know what could happen. Maybe try to follow him?
Maybe it's like back in the church, where you were in the same room, but not on the same "level" of reality. Follow him for a bit and see what he does!
