The Key of Dreams: Shadows Lengthen at Lemon Difficult Studio

The Key of Dreams is an award-winning, 24-hour-long immersive experience set within the grounds of Treowen, a 17th-century manor house in Monmouthshire, Wales. The experience combines fine dining, puzzle and escape room elements, improvised interactive performance, and branching narratives to create a one-of-a-kind, occult-infused immersive world that’s driven by the audience and their choices.

Since opening in 2024, The Key of Dreams has received critical acclaim, with BroadwayWorld UK describing it as a ‘masterpiece of dark, intense immersion’ and TimeOut calling it ‘as epic as it gets’. It was named as one of the best immersive experiences on offer anywhere in the world today and recently won the No Proscenium 2026 Audience Award for the United Kingdom, beating out the likes of Secret Cinema and Sage & Jester.
