One night, when my dad came home from a night out with his friends, he walked down the stairs and I saw a cousin that had died a while back coming down the stairs behind him. The only thing I can honestly say that frightened me was his eyes. Why? Because the ghost (my cousin) looked at me back with very wide eyes, like in a way the ghost was surprised that I could see him. When I turned to tend to my baby sister, he was gone. He appeared like a real person (in flesh). When my father came down stairs I asked him if that cousin have a twin brother and he said no, and then I asked "then who was the guy behind you?". My whole family froze. And that was the end of that story but I have others too.
Most of my childhood was filled with sighting and dreams I just don't remember them all, my mother remembers most of them. I never told anyone beside my family, my mom never let me, she always said people will make fun of me.
I see what my mother meant now people today really don't believe in ghosts or sightings of any kind but that's okay, everyone is simply different. I feel it's a gift from god. I love to read about sightings, it's great that there are sites like this one.
