This is my very first experience with the paranormal. Sorry if this is kind of short, but it was a rather quick happening.
I was four years old when this happened and I was playing outside of the house that I currently live in. I don't remember exactly what I was doing, but I think it involved me playing with a toy truck. My dad was also outside, but he was way in the back and I was closer to the back of the house. My mom and brother (who was only a toddler at the time) were in the house, so this could not have been the result of one of them.
I looked up from my toy and I saw something beside the back side of the house, opposite from the corner I was closest too. It looked like kind of what a Grim Reaper outfit looks like, tall and dark, in the shape of a person wearing a similar outfit. It was dark in the center of it but the edges of the 'body' weren't quite solid. They kind of misted out a black cloud/smoke looking substance. The figure just stayed pretty still for a moment, like it didn't even notice that I was looking at it.
It took only another second or two from there for it to see that I was watching it and it quickly darted away around the house. Being just a stupid, curious little kid, I followed it, wanting to see what it was. Of course by this time, it disappeared. I don't remember being afraid after not being able to see it any longer, because the memory is just a little hazy.
It didn't seem like a Shadow Man. Actual Shadow Men are supposed to be solid. It didn't look like a typical shadow, because it was more solid than that.
