It’s fun to be scared all year long, but during this time of year, it’s almost required. That’s why we’ve created a list of the 13 best scary TV Shows of all time. Grab a mug of something hot, a cozy blanket, and snuggle up to watch one of these terrifying tales. Just be sure to leave the lights on.

• “Alfred Hitchcock Presents.” Hosted by the famous man himself, “Alfred Hitchcock Presents” was a TV anthology meant to entertain and frighten. You may be familiar with the famous title sequence, where the camera fades to rest on Hitchcock’s caricatured profile, music begins, and then Hitchcock himself emerges to bid viewers a “Good evening.” The spooky show first aired in 1955, running for 10 years.
• “Are You Afraid of the Dark?” A children’s show on Nickelodeon, ‘Are You Afraid of the Dark?” may not have terrified adult viewers, but it sure scared the wits out of its target audience. The show centered on the Midnight Society, a group of teenagers that met weekly in the woods to tell scary stories. Children of the 90s will surely remember the show’s famous line, “Submitted for the approval of the Midnight Society, I call this story …”
• “Friday the 13th: The Series.” Running from 1987-1990, “Friday the 13th: The Series,” piggybacked off the wild success of the Friday the 13th film series, though the two were in no way connected. The show followed a set of protagonists who chased down cursed objects sold from an antique shop whose owner had sold his soul to the devil. It now lives on in reruns, achieving immortality on NBC Universal’s Chiller channel.
• “Goosebumps.” Another horror series aimed at young adults, Goosebumps is a television anthology based on the popular books of the same name, by R.L. Stein. The show’s episodes usually followed the theme of one of the Goosebumps books, with 43 of the original books making it to television fame.
• “Jekyll.” A BBC-based series, “Jekyll” follows the story of Tom Jackman, a descendant of Dr. Jekyll (from The Strange Case of Dr Jekyll and Mr Hyde), who has begun transforming into his own version of Mr. Hyde. Rather than being called an adaptation of the original novel, the show is billed as a sequel.
• “Most Haunted.” The first reality show on our list, “Most” Haunted is a British television show that investigates purported paranormal activity. The team and crew travels around the UK, and occasionally the USA, to investigate rumored hotspots and ghostly activity. Though the show isn’t as full of make-you-scream moments, the fear lies in knowing that it’s real.
• “Outer Limits.” Similar to “The Twilight Zone,” “Outer Limits” is an anthology show where each episode is a self-contained story. The original show ran from 1963-1965 and many viewers will recognize its unique intro which begins, “There is nothing wrong with your television set. Do not attempt to adjust the picture. We are now controlling transmission …”
• “Supernatural.” A current hit on the WB, “Supernatural” follows brothers Sam and Dean Winchester, who traverse the United States, investigating and fighting the paranormal. Like many modern shows in this genre, the show’s themes often center around American urban legends, such as ghosts, vampires and werewolves.
• “Tales from the Crypt.” Running from 1986-1996 and one of the few anthology shows free from censorship by the FCC (it aired on HBO), “Tales from the Crypt” knew how to frighten and scare like no other. Though the show shared its name with the 1950s comic, the show very rarely based its stories on the comic, instead choosing to dip into the blood and gore that the network allowed. The show won several awards and garnered a devout following.
• “The X-Files.” An Emmy-award winning show, “The X-Files” ran from 1993-2002 and captivated audiences with its stories of unsolved cases and otherworldly phenomena, investigated by FBI agents Mulder and Scully. The series sparked its own movie, which premiered in 1998.
• “The Twilight Zone.” Perhaps the most famous spooky show ever, “The Twilight Zone” was an anthology series written and edited by Ron Serling. The original series ran from 1959-1964, though it was revived several times. The episodes were famous for inserting fantastic experiences into everyday situations, often providing a  moral to the story.
• “Two Twisted.” The only Australian series on the list, “Two Twisted” features hour-long episodes of two stories each that always have twist endings. Episodes are written and directed by both experienced and inexperienced professionals, an element which gives the series its own twist.
• “Scariest Places on Earth.” Another reality television show based in the paranormal, “Scariest Places on Earth” investigates purported paranormal activity around the globe. Hosted by Linda Blair of Exorcist fame, the show has investigated haunted houses, spooky castles, and creepy hospitals. The show has been accused of fabricating events, so episodes should be taken with a grain of salt.
