Quagmire, also called the Dreamstride, the realm of Nightmares, is the plane of Oblivion associated with the Daedric Prince Vaermina. Every time lightning strikes, reality shifts to another horrifying vision. It could be anything, from a dark castle, a den of terrifying beasts, a moonlit swamp, or even a casket in which one sees oneself buried.
Sometime around 2E 430, Morian Zenas traveled to the realm. He experienced being in nightmarish scenarios such as being on a ship where all crew members were slaughtered, a den of ravening beasts, and being buried alive in a coffin, before quickly travelling to another realm.
During the Three-Banners War in 2E 582, Vaermina and her Supernal Dreamers cult captured the soul of High King Emeric and imprisoned him within a part of the Quagmire. He was later rescued by the Vestige, and Vaermina's plan was thwarted.
In 4E 201, Vaermina's Skull of Corruption has been instrumental for her to worm her way into the sleeping minds of the residents of Dawnstar. The nightmares they experience very likely occur in Quagmire.
