I was walking right after dusk with my 3 month old to try to get him to sleep. A car was coming behind me passing the intersection and a shadow person ran across the street about 2 houses in front of me and ducked behind the car in the driveway. I thought it was someone wearing all black with a hood on until I passed the house they ran to, and couldn't find them behind the car or any bushes. I replayed the instance in my head and realized how dark the figure was and that there were no facial features or any lighter shades whatsoever. I didn't see a face and they were nowhere to be found and definitely didn't go into the house. I went home and asked my wife if there was a such thing as a shadow person, because if so, I think I just saw one. She said she didn't know. When I googled it, I found out that they do exist, and from other people's experiences, I'm at least 95% certain that a shadow person is exactly what I saw. Especially when I remembered how it was ducking low as it ran across the street, as if to hide behind a hedge while running, or like someone running from someone shooting at them. It didn't seem to want anything to do with me, so I was lucky to have seen one of the good ones. I'll never forget the way it moved and that even though it was as black as black can be, I could still make out the arms and, legs, and head. I also know that it wasn't my shadow being projected by the passing car's headlights because there were no cars, trees or houses in the middle of the street...there was nothing for me to cast a shadow on except for the sidewalk in front of me. It was one of the weirdest things that's ever happened to me in my life.
