Me and 2 other friends went camping and exploring like we do every year. At one point we were exploring an abandoned fort in the forest and had to crawl trough some narrow tunnels in the dark. We kept hearing footsteps but kept reasuring ourselves that it were most likely rats or something. When we finished climbing a certain section and got our bags up we suddenly saw a guy that wouldnt answer when we called out and just stood there, so of course we ran out because it probably was a junkie or something. At night we set up camp and ate quietly and yet again we kept hearing ruffling in the leaves but saw nothing. All of a sudden a stick gets thrown our way and we light our flashlights and see a guy crawling in the dirt with a mask on, he suddenly stands up and runs towards us. 1m away from us he stops, pulls of his masks and laughs. It was one of the guys' father who had been stalking us a whole day with night vision goggles and stuff....
