WandaVision: 10 Insane Fan Theories You Need To Know
8. Nightmare Is The Show's Main Villain
Since Vision's return to the MCU was the immediate question on everyone's lips, the rumours and theories don't stop with Wanda traversing the multiverse to be with her love again. One of the easiest, and most logical ways to bring him back would be as part of a dream.
In this theory, Vision is merely a figment of Wanda's imagination, but what if Wanda doesn't know it's her imagination? She has created a world where her fellow Avenger is alive as well, but not by choice. She has been manipulated by another, and again, the key to this theory is the fact that WandaVision will link directly to Doctor Strange and the Multiverse of Madness. More specifically, the movie's potential villain.
Nightmare has long been rumoured to be the main antagonist of Doctor Strange 2, and was almost used in the character's MCU debut. He could also be the link between the show and the movie.
The villain is an incredibly powerful character in the comics, and is the ruler of the Dream Dimension. With the sitcom portion of WandaVision clearly taking place outside the realms of reality, Nightmare's influence would make a lot of sense, and could easily bridge the show into the Multiverse of Madness once Doctor Strange becomes aware of what is going on.
