Let's put it this way: Music/{{Tool}} are the fucking [=ExxonMobil=] of Nightmare Fuel.
[[caption-width-right:350:*dissonant guitar noises*]]
* "[[https://www.youtube.com/watch?v=uytWxYKSupI Rosetta Stoned]]." Has the {{Narrator}} been [[AlienAbduction abducted by aliens]], or is he just doing the MushroomSamba? Either way, it's ''really fucking scary''. [[WatchItStoned Listen to it stoned]].
* Here's something "fun" to do: stay up until 3 am, then turn off all the lights and listen to ''Lateralus'' all the way through. By the time you get to "Faaip de Oiad", you will be paranoid ''beyond belief''.
** "Faaip de Oiad"'s sample comes from a phone call taken on Radio/CoastToCoastAM from [[https://www.youtube.com/watch?v=0xpZHMMbhaY September 11, 1997.]] [[https://en.wikipedia.org/wiki/The_Faceless The Faceless]] also use that sample in "[[https://www.youtube.com/watch?v=MMQEcGNikfg Planetary Duality.]]"
* Tool songs fall under two categories, MindScrew, or NightmareFuel. The best ones do both, with often incredibly disturbing results. Take for example, [[http://www.youtube.com/watch?v=nbcKdc0xhNw&feature=related "Disgustipated"]] from ''Undertow''.
** The opening track on ''Undertow'' is just as bad. It's supposed to sound like someone running out of oxygen underwater.
* "Viginti Tres" from ''10,000 Days'' is another good addition to the list of creepy last tracks.
** The most notable moment is when suddenly, out of nowhere, a loud voice suddenly starts playing over the staticy sounds. A quite effective jump scare to say the least.
* "Prison Sex." While the original song is certainly more than enough to qualify for NightmareFuel, it's the music video that is truly disturbing. [[http://www.youtube.com/watch?v=F5sIXUbMgF0 Try watching it without feeling disturbed.]]
* Listening to "Die Eier Von Satan" for the first time can be intimidating: The incredibly dissonant guitar noises, backward drums, and vocals in a Hitler-esque German voice. [[spoiler: Until you find out what he is saying in English: [[NightmareRetardant it's just a German recipe for hash cookies. On top of that, the title in German may also mean "Satan's Balls".]]]]
** What about the interlude "[[http://www.youtube.com/watch?v=BvvC3BfMcZI&feature=related Cesaro Summability]]"? ''God''. It opens with a bunch of EarRape baby screams, then the whole rest of the "song" is made up of dissonant [[DroneOfDread guitar noises]] and talking.
* The music video for "Schism". [[UncannyValley Words alone fail to do it justice]].
** The music video for "Prison Sex" is even creepier, if you know what the song is about.
** The video for "Sober" is extremely unnerving.
*** There is no such thing as a Tool video that is not mind-meltingly disturbing.
*** Well, there's [[http://www.youtube.com/watch?v=EF_WKwbueG8 Hush]].
* Third Eye is terrifying. From the false buildups in the first 3 minutes, to the stoned howls of "PRYING OPEN MY THIRD EYE" and the chants of "I opened my eye, and there we were" are just like a nightmarish lullaby. I can only imagine what it sounds like stoned.
* And for the finale, [[http://www.youtube.com/watch?v=Ks5qyfxtYt8 Useful Idiot]].
** Which, as a joke, was put onto the album to trick people who brought the vinyl edition. During the day, it can be considered a joke. However, when played in the dark, it somehows turns into [[ParanoiaFuel paranoia fuel]] that sounds like it might cut to a [[JumpScare jump scare]].
