Nightmare is a recurring villain in Marvel comics, frequently antagonizing Doctor Strange. Nightmare also acts as the personification of nightmares and is often referred to as a demon prince of the dreamscape. He is also one of the Fear Lords.
Nightmare controlled one of the Splinter Realms known as the Nightmare Realm along with its benevolent opposite known as the Dream Dimension. His interference with mortals often caused him to come into conflict with Doctor Strange.
A man named Havelock revealed that twelve years before he (Havelock) first encountered Doctor Strange he had washed up on one of the Sunda islands. There he encountered an old woman. During the night, the old woman had to fight off Nightmare, overlord of the Dream dimension.
Approximately 800 years ago, Nightmare raped the demon Zilla Char, producing a daughter, Dreamqueen. Then, 350 years ago, Nightmare meddled with the Dreamqueen's schemes involving Native Americans.
Nightmare was fiercely protective of his realm, having warded off attacks from his daughter and other demons seeking to depose him.
Nightmare acted as a servant of Shuma-Gorath.
Nightmare expressed that he had grown bored and run out of ideas to torment dreamers with. He visited the realms of mortals to seek 'motivation.' He took control of a nightclub, renaming it 'Club Fear.' Patrons were briefly exposed to their nightmares. There he posed as owner Edvard Haberdash, becoming romantically involved with a horror movie actress.
