What are some ideas for a middle/high school haunted house?

i went to a haunted house last week and like at first when we walked in, there was this lady ahead of us screaming loud she was like 'there will be no screaming in my house' and things like that she then left, we kept walking and the haunted house turned pitch black. it was like a maze in the dark. there were like people with costumes on turning on flashlights and scaring us. then there was like a werewolf that jumped out and i was liek screaming and he was mocking me but yeah i got really scared try using a smoke machine for the begginging of it. oh and at the end there was michael myers like chasing us out i dont think ive ever screamed as much in my life OH and while we were in line, there was jason and scream walking up and down the line. and like jason came up behind me and i didnt know he was there and my sister was like' morgan look behind you' rofl :D
