My strangest story that happened to me when I was about 15 was when I was walking down an alley way (bear in mind that the two walls beside me were solid ) in broad daylight, as I was walking I felt the wind go straight passed my head and I heard a bang. It was in fact a stone, there was no way a stone could of been thrown in this alley way and the speed it came passed me was way too fast for it to be thrown by some guy. There was no damages to the walls just a single stone sitting in this alley way.
To this day I've always wondered if I walked any slower I could have possibly been really hurt or dead.. and the fact that I have no possible explanation as to how the stone even got there..
(Note I would have thought it came from above but I felt it go passed the back of my head from ear to ear)
