I don't know if any of you have ever heard of this, but there is an excellent ARG (alternate reality game), which is not a video game, called Marble Hornets. They use the paranormal entity, Slender Man, as the main "villain" in their story. The video series about a year old and one of the creepiest things that I have ever seen in my life. I'd thought that I'd share it with you all. It's best to watch this at night by yourself, not with friends... unless you have friends who will be serious during the video clips. The atmosphere will be that much better for your enjoyment... and worse for your mental health. Here's the backstory: YouTube - Introduction If you're really interested in anything scary, you must watch this. You will be weary of looking out of windows (you'll understand why), look over your shoulder time and time again, not want to walk outside at night alone, be a little hesitant to open doors, and so forth. Here is MarbleHornets's main channel, where all the videos can be easily found: YouTube - MarbleHornets's Channel Entry #26 is the best. You will have to watch #1 - #25 to really understand what's significant about #26, so don't just watch #26 and judge that for the whole series. ENJOY!
