I'm 20 years old as I write this story. What I am about to tell you happened to me and my brother when I was about 12 or 13 and he was 16 or 17. We had just moved into a house inside the city limits of our town and my brother and I would sit out on the front porch every night to talk.
One night, as we were both standing out there, we glanced towards the steps and looked right at each other with a scared look on our faces as we had both seen the same thing... What we saw was a man standing there, without a head, we knew it was a man because he was wearing a blue, long sleeved shirt and some blue jeans and his body was that of a man. When we looked at each other, he asked me if I had saw that and I said yea and he asked me what I saw and I told him a man with no head and I told him to describe what he was wearing, so I could believe that we had seen the same thing, and he described the man to me just as I had seen him. We ran inside and told our parents... who of course didn't believe us. But we were scared shiatless!
The following week I was in my room and had my windows open (during the day) and I saw a man pass by the window wearing the exact same clothes as the headless man and I ran outside, but since it was a quick glance, I didn't think of it being the headless man until I got outside and saw no one there. I thought it was my dad, but he was still at work.
Not very scary but at the moment it sure was!
