So yeah, when I was around 8 years old (in 2008), me and my brother decided to watch some random film we've found on our dad's computer.
At first, everything seemed normal, just a bunch of teenagers (I think it was a couple of guys and one blond girl) walking through woods. But then they hear shooting and find a dead deer. Also, there's a strange black pebble (like a polished small rock) next to it. From there on, creepy music started to play and the atmosphere got real scary real quick, and we, children at the time, didn't particularly like that and ran off crying for mommy.
Well, I remembered this encounter just now, and I want to re-watch this relic of my past. If anyone has any clue as to which movie could the described be, please tell me.
