The Sandman has a lot of deliberate nightmare fuel. Several of its characters are nightmares, and several stories are set in nightmares — and the bits involving real people in the real world can be even worse. The Corinthian is what happens when a nightmare seeps out from the Dreaming and enters the real world, causing massive damage to reality. Known for his terrifying teeth and appetite for human eyes, the Corinthian is an immortal serial killer who infects humanity with a similar bloodlust. Ann Ogbomo as the voice of Gault (season 1), a nightmare who seeks to become a dream while protecting children from abuse. Gault replaces the characters Brute and Glob from the comics. Roger Allam (season 1) and Wil Coban (season 2) as Lord Azazel, one of the Lords of Hell. The Sandman doesn’t need cheap tricks or gore to be dark—it goes deep into human weakness, pride, pain, and penalty. All of these moments linger with you not because they shock, but because they show you how gray the boundaries are between dreams and nightmares, right and wrong. These ten The Sandman moments take sleep away because they remind you that fear does not always hide in shadows. John Dee sits in a quiet diner and turns it into a nightmare lab. He holds Dream’s ruby and pulls every lie from his victims until they tear each other apart. Thus, the nightmares in Sandman are neither mere monsters nor evil spirits. They are conscious manifestations of the human need for fear, powerful and profound entities that evolve in a subtle balance between chaos and necessity. In the universe of The Sandman (comic by Neil Gaiman), Nightmares are a species of conscious entities that reside in the Dreaming, the realm ruled by Dream (aka Morpheus), one of the Endless, these incarnations of the great universal forces. The Sandman is a pretty dark fantasy with plenty of moments that live up to its reputation. For this list, we'll be looking at times that this series was more nightmarish than dreamlike. Gault is actually a completely new character and was created solely for the Netflix adaptation of The Sandman. She herself did not exist in the source material; rather, her character combines two. Upon escaping after decades of imprisonment by a mortal wizard, Dream, the personification of dreams, sets about to reclaim his lost equipment. While searching for an escaped nightmare in the waking world, Morpheus falls prey to Roderick Burgess, an occultist looking to summon and imprison Death.
