* "Three Evils" has what is probably the most disturbing EarWorm ever. "Pull the trigger and the nightmare stops, pull the trigger and the nightmare stops..."
* Also from "Three Evils" comes the filler track that segues into "The Crowing". It contains a slow, but rather creepy buildup that goes from street-level outside a pub to down in the sewers where a soft whimpering is heard that explodes into a loud "SKREE-" sound. It's used (at least, according to fanon) whenever an Onstantine Priest is lurking around.
* Coheed's "Welcome Home" [[http://www.youtube.com/watch?v=ycMNBgoWPZg video]] qualifies. And "Blood Red Summer" too, [[http://www.youtube.com/watch?v=bvH-70bY2C8 thinking about it.]]
* Claudio also made a quite graphic Willing Well IV: The Final Cut[[note]](which is, in itself, pretty creepy: ''"You're a selfish little whore, I'm the selfish little whore/if I had my way I'd crush your face in the door/THIS IS NO BEGINNING, THIS IS THE FINAL CUT...open up/THIS IS NO BEGINNING, THIS IS THE FINAL CUT...oh, I'm in love"'' - It's a DreamSequence where a character imagines themselve being taken to a guillotine and killed)[[/note]] video which shows himself (not in RealLife) torturing his (RealLife) girlfriend...creepy...
* "Ten Speed" doesn't have a very frightening music video, but the song itself is about a man arguing with his bicycle about killing off a fictional character based on his girlfriend. In the interlude, if you listen closely, you can hear a bit of their conversation.
-->'''Ten Speed''': But are you going to kill her off?
-->'''The Writer''': It's not your decision. I love her character, she stays.
-->'''Ten Speed''': Yeah, well the only thing love's done is put you in this position; I say kill her off!
-->'''The Writer''': Yeah, but you say a lot of things... how does that work? [[LampshadeHanging You're a]] [[MindScrew bicycle!]]
* ''The Willing Well II'': [[LyricalDissonance "You'll burn in hell while they're diggin' you out!"]]
* Much by Coheed qualifies as nightmare fuel, what with the lyrics about murder and all. Even if it is in the context of an epic science fiction story.
