1) If you hear a noise outside, don't investigate it on your own.
2) If a door opens on its own, don't walk through it.
3) If your flashlight suddenly stops working, go back.
4) If you hear an eerie voice calling your name, don't find out who it is.
5) Don't hide under your bed, in the closet, or in the shower, as these are the first places evil people look.
6) Don't walk through a graveyard at night.
7) If you're walking through the woods at night and think you see someone, don't check to see who it is.
8) Make sure and own a car with a push button start because if you're running from evil, you don't want to fumble your keys and drop them on the floor of the car, when you're trying to put them in the ignition.
9) If someone knocks on your door but you don't see someone out there, don't open it.
10) If something strange happens, immediately call the police. There's no use waiting for all the horrific things that will come next and then have the police arrive after all your friends and loved ones in the house have been murdered and you barely survived.
I hope you find the above useful. :)
