Did Eleven Build the Upside Down? What Is the Abyss? ‘Stranger Things’ Dimensions Explained

Published 12/27/2025, 8:25 AM EST

In Hawkins, the ordinary hums with unease. The school corridors, the arcade, even the quiet streets seem poised on the edge of something impossibly vast. Somewhere beneath, something dark watches, something that grew from curiosity, trauma, and experiments gone wrong.

The Duffer Brothers invite viewers of Stranger Things to explore a labyrinth where psychic powers meet military obsession, and childhood fears manifest. At the heart of it all lies a question both tantalizing and terrifying: did Eleven build the Upside Down, or is there something even older lurking beneath the Abyss?

Eleven did not intend to create the Upside Down, yet her powers became the catalyst. Under Dr. Brenner’s manipulative experiments, young Henry Creel, soon Vecna, was pushed into situations that warped reality. While her hands channeled psychic force and her mind flickered between worlds, a dark mirror dimension emerged.

The Abyss, the true otherworldly space where Henry originated as a child and the source of his powers and monstrous army, lies beneath it. Essentially, the Upside Down is a reflection of human meddling, while the Abyss is the uncharted core of supernatural danger.

Dustin’s investigation into Brenner’s journals reveals the Upside Down as a wormhole, not a separate universe, connecting Hawkins to the Abyss. Henry’s red, alien-like world birthed his abilities through trauma and a mysterious briefcase. Eleven’s genetic bond to him, a consequence of similar experiments, makes her a living conduit.

While military ambitions aim to replicate her powers, she is both weapon and target. Every psychic flare she emits reverberates through dimensions, threatening both human and otherworldly realms alike.
