If your including Stephen King Stuff, then I would advise you to not live in Maine. In fact, I would advise you not to live in the New England Area period, because that's where most Eldritch Abominations lurk.
If your the kind of person who, normally, doesn't believe in ghosts, you better start Freakin' Believing in them when your chairs are folded on top of tables, and when you feel a weird sense in the house. Nothing is worse then a Flat-Earth Atheist.
If you know there is a ghost/demon/Eldritch monstrosity in your house, leave, no matter how curious you are, no matter what anyone else says. Leave and never return.
Don't be the D-Bag that just records stuff happening. It's annoying. Instead, turn your camera off, and run like a bat out of Hell!
Also, never having sex is a +1 to your survival chances. It's not necessarily a guarantee, but it helps a lot. So, abstinence is the answer here.
