Intro. Level 37, more famously known as "Sublimity" or "The Poolrooms," is one of the most iconic and deceptively peaceful layers of the Backrooms. It’s a massive, sprawling complex of interconnected rooms filled with lukewarm, chlorinated water. While many levels are claustrophobic or terrifying, Level 37 leans into liminality—that strange feeling of being in a place that feels familiar yet deeply "off." The Poolrooms are defined by a sense of serene isolation. Imagine an endless, silent YMCA or an upscale spa that has been stretched to infinity. There are no windows to the outside world, no sun, and usually, no people. Comfort: The water is always the perfect temperature. • Nostalgia: The architecture mimics 1980s and 90s indoor pool aesthetics. • Dread: The realization that there is no exit, no wind, and the silence is heavy.
