Game Theory

So my mom used to play manhunt on the ps2 before I was born and she had this interesting theory. I have been playing it for a few years now, my mom and I liked Manhunt 2 more though.

Basically, everything James Earl Cash experienced in the game is in his head or his imagination before he's executed. She believes that the enemies in game are kind of his inner demons.

It's been a while since my mom has played this game and I just wanna know your thoughts on it.
