My old bed room in my parents house was haunted. They didnt beleive me for the longest time, i was able to describe what my grandma was buried in down to her necklace and earings. Mind you i have never seen a picture or anything. Fast foreward to my nephew who stayed in that room. He cannot and refuses to sleep in that room. He came downstairs one day, grabbed my sister walked her upstairs pointed into the air and said "mom, who is that guy right there?"
If you have never experienced anything like this, i would suggest staying away from it.
