I was sitting in my TV room once and there was a door with a glass window on the upper part of it in that room, and in the corner of my eye I saw a dead person with long hair looking at me, and then I turned my head to look at it and it was looking right at me and then i looked away, then looked back again and it was gone. Also when I lived in Colorado and I was much younger, my closet light kept turning on and off and it was switched off, so my mom came in my room til I fell asleep, then I woke up later that night to the sound of her screaming to the top of her lungs, she said a dead person with a kilt on floated over my bed and was staring at her. The next day--NO JOKE--my neighbor from down the street called my mom and said she "felt a prescense" at my house when she woke up in the morning and she came over with holy water and did some weird ass ritual at my house, the only reason my mom let her was because she says she actually saw a ghost.Another time I was home alone and I heard someone run across my attic floor in what sounded like high heels or tap shoes or some crap it was really scary. I definitely believe in ghosts. I guess I believe in aliens, though I've never encountered something like that before.
