My theory is the fact that oswald when he i guess jumps when entering the office that theres a hole behind us not exactly a hole more likely a exit door oswald basically jumps right thro that door and back to where he started you will mention the fact that theres not a door behind us well.. another theory is the fact that slester when jumpscaring basically hides the door because well... so we dont escape? back to oswald the thing is the reason why i think its real its because lets be real here since he jumps when he enters the office like we mentioned, and we hide he would hit the wall so thats why the door theory even exists because it wouldnt exactly make sense why would he go STRAIGHT into the wall?
