theres 3 points of why not to do it:

1- im lazy and stressed enough to create a new story to fit the game.

2- the original story is literally a copy of FNAF lore

3- garvey is an edgy fucker lol.

basically if u ask how tf did we reach to dormitabis reboot:

You are trapped onto dormitabis reboot; bc u were a serial killer.

Since u were one of the biggest fnaf fans, now u are locked onto that purgatory having to suffer the agony of the ones you killed converted onto cursed animatronic creatures ready to hunt you.
