Sometimes it's easy to forget that Supernatural is a horror show. Over the years, the series has found itself moving more into plot-focused seasonal arcs about the war between Heaven and Hell. While cool and all, that has arguably shifted the series from the realm of horror and into a completely different territory.
Even if it may not resemble much of the the cult horror hit it started as, over its 15-year run there have still been many spine-tingling episodes to be found. Supernatural has pulled from every corner of the the genre, and even crafted some of its own original ghost and ghouls that go bump in the night. In fact, the early adventures of the Winchester brothers contain more genuine nightmare fuel than you can shake a stick at.
J-horror inspired ghost girls, killer clowns, and spirits of serial killers past, Sam and Dean have seen and hunted it all.
So turn on the lights because it's time to take a walk down memory lane with a look back at the scariest episodes of Supernatural.
