• Nightmare Fuel:
  • Not surprisingly, "A Virtual Nightmare" is full of this. The main character finds a virtual reality headset which traps users inside and has to defeat all enemies to escape. However, the enemies are actually other players who die when killed.
  • "Realistic Minecraft". It starts out as a typical Minecraft experience, but once the player (in first-person view) gets his hands on diamonds, all hell breaks loose. He begins fighting for his life against real-life versions of hostile mobs, including a Creeper that looks like a green, armless humanoid with Spider Limbs for its legs. It's quite scary enough, but the crowning moment for this video is Herobrine killing the player at the very end; terrifying indeed.
