Okay so me and a group of friends were walking through some backstreets and we were talking about paranormal stuff and weird things that happen to people and we all are just staring forward while we are talking and we saw this tall slender shadow with a distinctive human figure absolutely zoom past in the distance appearing to be gliding around half a metre in the air and my group and I speed up to have a look where it went and there was a car just parked there with its headlights on just waiting there and the figure was gone and the car drove off but we didn't hear the car door open nor close. please share your thoughts on what you think it could be?
