True Blood/Nightmare Fuel

• The bald vampire doing Maudette Pickens. *shudder*
• Malcolm, Diane and Liam having that upside down body in their house, blood streaming from her headwounds into a bucket.

Malcolm: She felt so bad about what Jerry did, she made the ultimate sacrifice.
Bill: You all make me sick.
Diane: You used to be fun!

• Tara's exorcism. She saw a little girl version of herself, which she had to stab, after which there was blood on her knife. It becomes even more creepy when Maryann reveals she was drawn to Tara because of this ritual, and the child-Tara with the big black eyes was what Tara looked like in Maryann's vision.
• Eric killing Royce the redneck by ripping him to pieces.
  • And that scene manages to become even more Squick when Lafayette pulls Roy's metal hip out of his severed leg and frees himself with it.
• Sookie being attacked by that creature who turned out to be Maryann. Cue the scene in which Dr Ludwig removes the poison from her incredibly deep wounds by running her fingers through the gashes.
• Heck, Maryann's entire trick of turning people into black-eyed zombies could qualify. It was Played for Laughs with a few characters, but to see Eggs and Tara beat eachother up than have rough sex while Maryann's giggles with joy was disturbing in it's own right.
• Maryann's wedding, beginning to top - from the bridesmaids theme, to stabbing Sam, to Sam in bull form ripping Maryann's heart out.
• Bill and Lorena's sex scene. Squick.
• Lafayette's scary visions after Jesus awakens his inner witch and makes him into a medium. For one, he sees Sam with bloody hands, whispering a threat in a low voice, making the usually comforting character very disturbing and scary, and then he manages to witness the ghost of Rene grasping Arlene's throat and saying he's inside her.
• The spirits in season 4. They jump at the viewer in a very unpleasant way.
• In hindsight; Bill having sex with Portia Bellefleur, Andy's sister, who turned out to be his great-great-great-great granddaughter. It became even worse when Portia actually wanted to continue the relationship.
