One night you felt like camping by yourself in a large and foggy forest, it had been said that it was haunted and a negative and horrible energy, but you didn't care, after all it is the woods alone what could go wrong?....many...

There you were in a area of the woods surrounded by thousands if not millions of large and tall and weirdly eerie looking trees. The air was thick with fog but a fresh air smell aswell, there was crunchy leaves under you any where you were, and under your tent

As you were putting your things in your tent from your car far away from the location you would be camping at alone, you would see a tall and fogged up tree with a loose and crumbly peice of text book paper, stapled to the tree which said 'RUN' in a graffiti way, and the letter were red and to weirdly like blood. You thought it was just a prank from other people staying here before you, so you walk back to your tent which has no cell service
