(You arrive at a school you're meant to investigate, many missing persons reports, you essentially break in and begin investigating, once you enter you go to turn on the breaker, and after doing so, you suddenly fall through the floor, and your camera glitches out, then you wake up here, in an alternate version of the school. You have now entered "The Classrooms".
Begin investigating around, try exploring around, and try to find a way out or perhaps deeper in.)
