Or it was just a fridge that was small and confined like the room he was in when he was in the nuthouse.
Or maybe he is still in the nuthouse and that's why the refrigerator looks like his cell? lol
why do you want this all to be made up so bad? it makes for a much much worse movie.
I don't want it all to be made up. But some things point to that it might be the case. Or a large part of it. Just discussing options.
I'll probably go see it again to look more closely at things and clues that might be in the movie.
