I know someone who's like that. They've been around haunted houses since he was young(his mom was even choked out when sleeping before). We went through a old Civil War era battlefield one night and he saw a ghost dead body laying near a memorial.
I don't know if they just pick the wrong houses to live in; but I've heard a girl laugh next to me one time. I thought it was coming from the window(either their mom or neighbor) since I was laying on the bed with my head by the window. Looked outside, no one. Later when I asked if their mom was home, they told me she had left somewhere with the neighbor. I shrugged it off and thought maybe I was just hearing things. Anyways, a couple of weeks later, my cousin was there with just his sister and the dog. They heard the same laugh coming from the door while in the room and the dog was freaking out. When they described the laugh that's when I was like "Oh shit, I heard that same laugh".
Anyways, my mom has seen a ghost back when she was in Viet Nam sleeping along a trail. She knew it was a ghost because it was her dead cousin. Anyways...she chased it into the woods with a butcher knife and challenged it to come out. lol. FOBs have some CRAZY ghost stories man.
