The location of Vecna's physical body in the Upside Down's version of Creel House seems to be the reason why the home's pieces float in the red smoke world. When Max is cursed by Vecna and possessed, her body is still in the same place as Billy and Nancy, but in the Upside Down. The victims of Vecna's possessed in the red smoke area can only escape through their favorite song blasted into their ears and the happy memories of their loved ones. Vecna still lives in the Upside Down version of Creel House, but his possessions of Max and Nancy can be seen entering a different location filled with red smoke and floating pieces of the house. The boiler room in the dream world is a place for Freddy to trap and kill his victims, like Henry Creel's mental red smoke area in the fourth season of Stranger Things.
Vecna's red smoke area will be eliminated alongside Henry Creel/Number One, as it only exists within his own mind, since the full truth of its history is unknown. When Max is placed on a tree in the red smoke area, her body isn't actually there, but rather is placed in the mental location as a memory for Vecna's strength.
Vecna's red smoke area is similar to Freddy Krueger's boiler room in A Nightmare on Elm Street's dream world, which served as Freddy's hideout both in life and death. The villain's mental red smoke area would cease to exist if the characters destroyed Vecna's connection to Creel House. The victims of the monsters resided in the Upside Down because of the Mind Flayer's possessions. It is believed that Max and Nancy had a significant power when they were able to see Jamie Campbell Bower's Vecna. Freddy became stronger through the memories of trauma and emotions of his victims, with his victims also becoming part of him in the dream world. Max and Nancy discovered a way to escape Vecna's mental world that could allow them to get away from their possessions.
Vecna's personal red smoke area is not the Upside Down when Max and Nancy enter a terrifying trance.
The red smoke area and the Upside Down are different places in the fourth season of the show.
In the season 4 episode "Dear Billy", after Max is possessed,Dustin theorizes that she invaded Vecna's mind, which is why he was so surprised by her appearance. Unlike the Upside Down, only one's mind or essence can be sent to the red smoke area. This suggests that once Vecna/Henry Creel has taken a victim, he absorbs their trauma into his mind, making him stronger as he creates an army in his own red smoke-looking subconscious. Vecna's red smoke area isn't the Upside Down, but a location inside his mind. Vecna mentioned that when he kills, each of his victims becomes part of him, with the villain pointing at his head.
Not all victims can reach the red smoke area as Max and Nancy were in his mind. Nancy was transported to the location while still in the Upside Down. The red smoke area doesn't seem to exist when consideringDustin's theory on Vecna's curse. There are things to know about the fourth season of Stranger Things. There is a warning!
