suspence

Joe cautiously walked into school.The door creaked as it slammed behind him.He turned around not noticing what was wrote on the door.It said turn back or else.He slowly looked up a strange stream of blood led to the old rusty metal toilets.Suddenly a holler came from the girls bathroom.Joe heard it loud and clear.
Hello is someone there he said.He felt a slight breeze it sent a cold shiver down his spine!He noticed he wasent in his school where was he?
