In this video, we break down Stranger Things Season 5 Volume 2 using Dustin Henderson’s science-based theories to explain the Upside Down, Dimension X, wormholes, and Vecna’s true plan. Is the Upside Down really another dimension — or a failed science experiment created by Hawkins Lab? Why is time frozen on the day Will disappeared? And how does Dimension X connect to the Mind Flayer and Vecna? This explanation uses wormhole physics, parallel dimensions, and clues from previous seasons to predict how Stranger Things Season 5 Volume 2 could finally end the Upside Down forever. ⚠️ No official spoilers — theory-based explanation only.
