Netflix isn't just for chilling... it's also for chilling, as in scaring yourself silly. Here are some of the scariest episodes of our favorite shows featuring creepy clowns, headless witches, bloodthirsty ghosts, serial killers, and spooky hitch-hikers.
Many of these work great as standalone eps, such as "Supernatural," "The X-Files," and "Bones," and of course, the classic "Twilight Zone." Others, like "The Walking Dead," are better off experienced as a terrifying whole.
You've got enough time this Halloween to stream all of these 21 episodes, especially since several might keep you up all night.
