This is gonna be so great. Finding supernatural things with good people, trooping through haunted forests, maybe seeing some aliens. Sounds like a great time.
I know about a creepier forest. It's called Aokigahara. It's situated at the base of Mt. Fuji, Japan and it's a place where people go to commit suicide, therefore known as "the suicide forest". There's a movie coming out about it, don't know when though.
This place is an awesome place to read about ^^
