Someone please help me out a bit.I'm looking for really GORY and SCARY ideas.?

Okay,I'm 14 years old,and I want to make scary stories.I like the REALLY REALLY gory and spinetingling tales.I DO NOT want to copy any scary creator's work.I just want IDEAS.I want to write a really,really,scary story for my teacher,Mrs.Wade,just to freak her out.I was thinking of vampires,but I decided against them.She is 27 years old,and she should be scared by very very gory stuff.Werewolves are AWSOME,but she'd be saying something like,"Okay..."I want to REALLY freak her out.Scare her,you know?So can some people please give me IDEAS?
