Slender
It was a peaceful night while a man that was 27, was driving down the road past an old abandoned recreation site. When his car started sputtering and making noises, he checked every thing and noticed his gas light was on. So he pulled over and waited about five minutes before deciding to hop over the fence with a flashlight and look for anyone inside the old recreation site or just gas. And he was walking around he found a note paper on a tree. He picked it up and then it got real quiet, no more birds, wind, nothing just emptiness. So he stood there for a few minutes and started walking again, then he thought he heard something behind him and turned around. No one was there, at least he thought, so he yelled "hey! Anyone out there!"... no reply, so he turned back around and could see a large tunnel ahead. So he started walking a little faster and found another note on the side. It said "Don't look, or it takes you" now the man has two notes and is slightly scared.
Now he's kinda speed walking a little, he see's a group of rocks in a semi-circle. He walks around it and finds another note! It says "NO NO NO NO NO NO" now the man is really scared and see's something in the distance. He see's a very tall man, in a tuxedo, and a white face with nothing on it. At first he feels fine then a pain in his head starts hurting and he's having trouble seeing. So he turns around and starts running also while realizing that as hes not looking at him he feels fine. So he gets tired and slows down, wondering if he should turn around he does, he doesn't see him and find a note that says "Slender Man" as he turns back around 'Slender Man' is right in front of him and the man is shocked, then has a heart attack and is to never be heard of again.
