Please don't list this on a work's page as a trope. Examples can go on the work's YMMV tab.
Nightmare Fuel: Bones
'The Girl in the Fridge'. The title reference is to a victim who was held captive in an old refrigerator and suffered increasingly worse pain because she couldn't turn over. And all the killers did was keep her quiet by giving her more and more drugs.
The murders of the girls in "Two Bodies in the Lab" - torn apart by dogs, amongst other unpleasant things. And the fact that it could have been Bones' fate at the end if Booth hadn't showed up.
"The Man in the Cell": The whole episode was downright scary.
"The Man in the Morgue" - the way it's shot, the way the murders are performed. All of it.
The Season 7 finale. An ever increasing exercise in paranoia.
Season 7, episode 2. The snake is hidden in the body, alive? Argh!!
PamNunan from "The Wannabe in the Weeds". Her stalking of Booth is deeply unnerving.
