I was about 14 when this happened to me and was living in San Jose, CA. Ever since I went to my school, Davis Middle School, outside the track where we ran there would be flowers for someone that passed. It was at the bottom of hill lined with houses.
One day I was at my house and my one of my friends ran into my house freaked out. It was like 1:00 am. He told me he was at a party and that they saw a group of ghosts walk up to the entire party. So I asked him where. He told me at the hill.
The next day I guess my friend told another one of my friends and his girlfriend and took them there. Again they ran to my house and said that a ghost followed them through the school. They were super freaked out.
So I got my friend Louie and we went to the top of the hill and we didn't see anything. We yelled and taunted for him to come out but nothing. So we walked home.
Like 5 months later I went to a friend's house and was walking home. It was like 3:00am. So, not thinking, I walked down the hill and would cut through the school. So I'm walking through the school and I felt like someone was following me. I could hear someone walking behind me and it's on asphalt. So I stopped, turned around... Nothing. I could hear it again so I stop. Nothing
So I make it out to the school. And I'm on the sidewalk and I'm kind of thinking to myself like, "Wow, you're such a wussy, really" and then I turn my head and look into the parking lot across from me and there's a bright white lit young man in a suit standing looking at me. So I turn my head and I tell myself, "You're trippin." So I took two steps and turned my head again and this ghost is two feet away from me. I could see his tie, his hair, his eyes, but it's all transparent. I have never been that scared in my life. I ran the rest of the way home.
I guess some kid who went to the school was run over by a car at the bottom of the hill. RIP whoever you are.
