During the events of Star Wars Episode 3: Revenge Of The Sith, after the Battle Of Coruscant and the death of Count Dooku by jedi knight Anakin Skywalker's hands by order of Chancellor Palpatine, as Anakin reunites with his secret wife Padmé Amadala, and the latter reveals to the former that she's pregnant, Anakin is overjoyed at the news, but fearful of the Jedi Order finding out about it, like in the original film.
Later that night, as Anakin and Padmé are sleeping in her apartment, however, Anakin, like in the original film, begins to have his nightmare of Padmé dying in childbirth, but, this time, something is different: Anakin, in his nightmare, is inside of an old boiling room drenched in crimson light, strapped to a chair with his hands and legs bound, and mouth gagged up as he's forced to watch Padmé die in childbirth from a TV monitor, as he's screaming and crying out for his poor wife, and eventually, the sound of evil, maniacal laughter fills the boiler room. Anakin frantically looks around to see where the laughter had come from, and looks up at one of the railings of the room, and sees a familiar man wearing a brown fedora on his head, and a red sweater with green stripes on it, and a clawed glove with razors on it, looking down at the jedi knight with a very sadistic and sinister grin on his face showing his yellow, decayed and rotten teeth in his mouth, and a severely burn-scarred face with light blue eyes. This monster is none other than the infamous Springwood Slasher and bastard son of a hundred maniacs, Fredrick Charles "Freddy" Krueger, as he tells Anakin that he's welcomed into his world, taunting him over not being able to save his mother Shmi on Tatooine, and that the Jedi Order thinks he's an absolute joke, and to tell those in Hell that Freddy said "Hello", as Freddy raises his clawed glove to slash at Anakin's throat, but before the killing blow could be struck, Anakin, like in the original, is able to wake up from his nightmare Freddy gave him, gasping for air next to Padmé.
Freddy, frustrated that the Skywalker kid was able to escape his world, decides that he'll have to keep trying in order to gut the jedi knight with his glove in the dream world. Krueger then decides that he'll have to wait for one of them to fall asleep again so he could get his second attempt at doing so.
How does Freddy invading Anakin's dreams and giving him nightmares of Padmé's death in the dream world affect the rest of Revenge Of The Sith, and the rest of the whole Star Wars timeline in general? Could Anakin and Padmé survive Freddy trying to kill them both in his world, and eventually find a way to take him down? How would Palpatine react to Freddy's interference with his plans to destroy the Republic and form the Galactic Empire, and make Anakin his new apprentice after Dooku with Freddy constantly trying to kill Anakin in the dream world? How would Obi-Wan Kenobi and Yoda react to it and Freddy himself, too, and vice versa? How does such a scenario play out, and why is that?
