Haunted school

You are the only alive person in the school Or are you...? One day you heard a sound...creeping up the room of Class•3023•......Then you saw it ghosts and demons you are all alone so plan the...escape... "AAAAAHHHH!!!!" You hear a living boy scream hearing tearing and blood or water....Dropping on the ground the sound filling the halls. You see a letter and read it Dear, Jade I want to know a story of a missing person well more than 500 people I mean a school burned down and no one survived but the school got rebuilt but no one built it back and if you stay in there...You don't want to......Really know I'm sorry... Do you see anything or....anyone?
