''VideoGame/{{Rayman}}'' has several examples of NightmareFuel, notably most of them in the [[DarkerAndEdgier second game.]]

----
* [[IDontLikeTheSoundOfThatPlace The Cave of Bad Dreams]]. The cave itself is made from nightmarishly grotesque faces, for most of the level, you're riding on skulls across what's pretty much the river Styx. Next you have these wooden claw-like things that sweep out at intervals on the wall, if you get caught by one, it slams Rayman around before dragging him into its hole, where he loses some health and respawns. Next up, we get the mini-guardians, these things aren't much of a threat on their own, but if they get close enough to Rayman, they'll swallow him whole and alive for hp loss and a respawn. At the very end of the cave, the Guardian arrives and attempts to eat Rayman, the camera switches to ShakyPOVCam of his mouth as you attempt to escape him on a slide.
* The Tomb of the Ancients. There are skeletons everywhere, the wall design is very similar to the Cave of Bad Dreams, and it has another river Styx boat ride This time you have to fend off zombie chickens on a very small barrel; once you get to the end of that area, you find a pitfall. The tempo of the music changes to PsychoStrings after you get down to the bottom, at a tempo played to simulate something skittering towards you from the darkness, right before a GiantSpider attacks you.

* Most of The Desert Of The Knaaren from the third game.
