Nightmare Fuel / Boy Meets World

  • Season 6 had the appropriately-named "The Psychotic Episode". As if the main plot of Cory having nightmares in which he kills Shawn wasn't bad enough, the subplot with Eric's new roommate could be stretched out into a full horror movie! The man keeps the corpses of his mother, uncle, grandmother and pet parrot around and makes them talk! Plus, it's implied he killed all his other roommates.
  • The flashback to Rachel accidentally destroying her stuffed rabbit in the garbage disposal is a bit unsettling.
  • The tarantula in the Honeymoon episode can be unsettling to arachnophobes.
  • The twist to "And Then There Was Shawn": the killer was Shawn himself... trying to get Cory and Topanga back together (since he feels them breaking up was his fault).
    • Pretty much every part of "And Then There Was Shawn" not played for comedy is terrifying. There's blood, explicit mention of death, impalements, and more. And the "strange, shrouded figure creeping behind us that none of us will see" is played for laughs, but the killer is terrifying with his skull mask. Good luck sleeping after watching it.
