I've been near Slenderman. I'm guessing since you've clicked this topic you want to hear my story, so here goes.
I was out camping with some friends when one of my friends told us a story about "Slenderman". He apparently stalked people for years, until eventually killing them. I already knew about Slenderman, but I decided to listen anyway.
In his early encounters, his main dish were children. He took out their organs and put them in bags. He then showed me a photo he had in his backpack of Slenderman. It was the original one with the kids at school and Slendy in the background. It was midnight, and I decided I didn't want to hear his story anymore, so I went into my tent and went to sleep.
I was awaken by some grumbling noises outside of my tent. I went outside to investigate. I saw Slenderman in the trees. "EVERYBODY, WAKE UP!" I yelled! My vision was distorted, and I didn't want to die. Everybody woke up. I yelled, "SLENDERMAN IS IN THE FOREST!" and of course they didn't believe me. They decided to look anyway, and they froze. I ran while Slenderman was busy picking off my friends.
I feel guilty for letting my friends die, but it was for my own good. I still see Slenderman up in the tree in my backyard, slowly waving, distorting my vision, but I ignore it usually. He's after me still, but I'm still alive. I can ignore him. I can live my life normal. I can forget this moment. I will forget this moment. It's just a blur, I need to forget it. He's looking at me through the window right now, waiting for just the right moment. I won't give him the right moment.
