So I just watched one of the newest game theories that says fnaf 4 is impossible. While I watched it, I got my on theory.

So the kid was having nightmares. Impossible without a frontal lobe, right? What if this was before that happened? I know you are saying "But Shiny, he was in a hospital!" I know. But what if the nightmares got so bad he had to go to the hospital to help them? What if the reason his brother locks him in his room is to keep him safe? And that whole thing with the brother putting on a Foxy mask, what if that was a prank for his friends? Then that means the brother actually does care about the protagonist which is why he tries to get their frontal lobe out, to stop the nightmares! That could be what night 9 actually is! And since Fredbear thinks he broke him for a bad reason, he apologizes. BUT, the kid cries over loses them. That could easily mean he got over his fear and wants to be friends with them!

So yeah. A lot of what ifs but those are always present in theories. Tell me what you think! Don't be afraid to try to debunk it, I'd actually appreciate to know other things that could make this true/false.
