Dementia casters like Chainer, Dementia Master and other members of the Cabal on Otaria have the unique ability to summon horrors from their personal "dementia space", a place populated with the caster's greatest fears and all beings he or she has killed. These so called Nightmare Horrors appear also in white, blue, red and green.
The nightmares of Innistrad are twofold. One variant has little in common with the equines encountered on other planes. Instead, they manifest as spirit-like entities that torment sleepers (Persistent Nightmare). Others resemble classical nightmares and are closely tied to the demons of Ashmouth. (Stallion of Ashmouth)
The Nightmares on Ravnica are aligned with the Rakdos. They resemble an eight-legged, two-headed horse with fleshless heads that are carnivorous. (Carnival Hellsteed) There are also a Nightmare Sphinx and a Nightmare Demon associated with the Dimir. During the War of the Spark, Ashiok created their own brand of nightmare.
Ashiok is a planeswalker from an unknown plane who discovered not only a great skill at culling the nightmares from others, but also the ability to make them manifest in reality (Ashiok, Nightmare Weaver). Ashiok enjoys watching those who see themselves as untouchable and superior reduced to screaming and blubbering. Because all sentient beings feel fear, Ashiok believes in its power as the great equalizer.
The nightmare mechanic was designed by Richard Garfield for the Odyssey set but later moved to Torment. Torment featured seven black Nightmare Horrors and two red Nightmare Beasts. Judgement featured three red "Gorger" Nightmares and six blue "Wormfang" Nightmares.
Whenever one of the a Nightmare creatures, as featured in Torment, comes into play, another card (of a type specified in the Horror's rules text) in play or in hand is removed. When the creature leaves play, the card it "replaced" is returned to play. Some nightmares make an opponent lose and gain life respectively, instead.
Each of the blue Nightmares of Judgement requires the loss of a particular resource, usually permanents, excluding the rare ones, which take a turn or your hand, but return them on leaving the field. There are two vertical cycles in this category. —Wormfang Drake and Wormfang Newt in common, Wormfang Turtle and Wormfang Crab in uncommon and Wormfang Behemoth and Wormfang Manta in rare.
