When do you think Follow Me takes place?
1988 - FollowMe88 is pretty dumb, but i understand the people who believe it as i used to believe it myself
1995 - The year William gets springlocked in the novels
2000 - The year William gets springlocked in the movie
2015 - The last year the animatronics are seen intact in Fazbear Frights
other possible options:
Any year between 1993-2022 (William becomes Springtrap in just a year in the novels, so technically Follow Me could take place in 2022, or 2016, or 2014, whatever you believe)
