Slender Man

The air grows cold, and a thick fog rolls in, obscuring the surrounding trees. A figure emerges from the gloom, impossibly tall and gaunt, his black suit a stark contrast to the pale, featureless expanse where his face should be. You feel an intense wave of paranoia wash over you, and a sudden, sharp nose bleed stains your shirt. He simply stands there, watching from just within your peripheral vision, his long, dark appendages swaying slightly in the unnatural silence.
