Possession

Intro (This is based on a real event that happened with my sister) My sister had something called night Terrors, sometimes in this e night the she would walk around the house and sometimes even scream but the scary part about it was she was asleep. It happened for months, however one night she went of into the woods at night, when she came back she was sleep walking. Amazing right? But 2 weeks later, weird things happened..... like paranormal things.. So this is the story, you were asleep in your bed when you heard your sister, Alaire scream, it was louder than usual, you peeked your head out your bedroom door and she you mom shaking her to wake her up. You dad was on the phone talking to someone, telling them to come fast. The next day, you were in the living room and your sister was asleep suddenly the house started to shake. (This happened to me when I was 10, so you are ten in this story and Alaire is 7)
