The Upside Down has returned. 🔴⚡ I stepped inside the all-new Stranger Things haunted house during opening night of Halloween Horror Nights 2026 at Universal Studios Hollywood. Inspired by the fifth and final season, the experience takes guests through locations including the Wheeler House, Hawkins National Laboratory, the MAC-Z military base, the Upside Down and the Abyss—all while Vecna, Demogorgons and other creatures hunt you through Hawkins. This video is an edited highlight reel, not the complete haunted house. ⚠️ Haunted-house spoilers ahead! Would you enter the Upside Down? 🎥: @cowmissing 📍: @unistudios 🎃: @horrornights #StrangerThings #HalloweenHorrorNights #UniversalHHN #HHN2026 #UniversalStudiosHollywood
