I was about 12 or 13 and me and a friend decided to go and screw about in the woods, anyway we end up in this field which we eventually found, thought it looked strange and completely abandoned so we decided to jump over the barbed fence and go into it. not more than 2 minutes of walking into the field I look to my right and there was a human shaped figure leaning on a fence, it was about 10 meters away but the figure was entirely black, just pitch black, like a shadow moving of its own accord. I knew immediately that it wasn't something within the ordinary so I sprinted back towards my house, my friend followed suit and its not uncommon for him to see things I see. Eventually I got back on the path and I asked him why he was running, expecting him to talk about the shadow towards the top of the field, he said he had seen a child in front of him that appeared out of no where. Its haunted both of us and neither of us have gone into those woods since. I've had experiences which were closer than that but they weren't as negative so I haven't really considered them as much.
