Upside Down (Stranger Things)

The Upside Down is a fictional interdimensional wormhole featured in the Netflix science fiction horror series Stranger Things, created by the Duffer Brothers. Introduced in the first season (2016), it serves as a central antagonistic force and setting throughout the series, acting as a bridge between Earth—specifically a frozen-in-time replica of the town of Hawkins, Indiana—and a chaotic alternate realm known as the Abyss.
