I have a similar story from Ghouls,
Me and my 2 friends were bored and decided to climb up a wall (cinder block wall)well the wall goes about 1/2 a foot up every persons back yard it gets a lil bigger but it was a long wall. On the left side was peoples backyards and on the right side was just a side walk. As we start going up a few feet almost to the end where you can jump on a giant rock to get off, suddently theres a tree hanging from a persons backyard over to the sidewalk basicly, So my friends are in front of me and they are going through the tree so they had their hoods on and so I pull mine on to not get leaves in my hair or somthing, as im crawling under this tree a lady comes out and shes the one with the tree in her backyard she says "You guys better be careful" and im still crawling through and I ask "why?" she sayed that theres 3-4 inch needles in the tree and I stop and almost felt like stuffting a brick, then I move my head and wham a needle comes about half an inch from stabbing my eye, scared stuffless I say "guys.." they were like "yea?" I said "forget you guys im bailing", and fell off well since we were near the end I ended up falling off a 8-9 ft. wall and landing on my back.
Tl;dr: I was climbing a high wall and a needle almost stabed my eye and I ended up falling off a 8-9ft. wall landing on my back.
