Stupid ass theory that I came up with at 4 am: Bonnie (or maybe the spirit possessing him) is aware that he's a videogame character, since at 0:37 he explicitly says "you PLAY again, and it's usually me to be the first disturbing being that you see". This directly references the fact that in FNAF 1 he is the first of the animatronics to start moving around on the first night, and it also makes absolutely no sense for him to use the word 'play' in the context of this situation otherwise since the nightguard would definitely not be having a good time (and the animatronics are very clearly aware of that since he flat out threatens to kill us in the song). Matpat should hire me /j
