We Bet You Won’t Watch These Terrifying Horror Movies Alone

What makes a movie truly terrifying? Is it flesh-eating zombies? Vengeful spirits? Or perhaps a crazed serial killer with a penchant for the taste of blood?

The scariest movies leave us spooked even after we leave the theater because they play to our greatest fears and phobias. Psychology Today says there are specific elements that make movies scare us, including things like death, the dark, generally spooky places such as graveyards and overgrown forests, suspense, disfigurement, and dismemberment (yikes).

While opinions vary on the scariest movies of all time, these horror flicks are undoubtedly chilling and probably shouldn’t be watched alone. See which ones made the list.

The Film That Gave People Claustrophobia (And Nightmares)

Released in 2005, The Descent tells the tale of a group of innocent young women who go spelunking in the mountains of North Carolina. All seems well at first—that is, except for the ever-building anxiety that something is about to go terribly wrong.

As the women meander through the cave, they realize that they’re terribly lost and can’t find their way out, leaving them disoriented with a limited amount of light. As if being lost within the depths of a dark cave isn’t already scary enough, they soon discover that they are not alone.

The flesh-eating humanoid who inhabits the cave makes your run-of-the-mill murderer look like Mr. Rogers. The women must fight their way out in a suspenseful gore-fest of a film that isn’t for the faint of heart. The combination of the otherworldly creature coupled with the chilling thought of being lost in a cave with no light and no way out is sure to make even the bravest film watchers uncomfortable.
