Ok, so it’s a dance club. Except there’s no music. And to get in you need to wear tap dancing shoes. And the dance floor instead of being dark, is EXTREMELY bright. Like painfully blindingly bright. So all you see is bright light and silhouettes, and all you hear is just constant taptaptaptap of feet shuffling and dancing on the dance floor. Mixed with groans of pain.
Like, imagine just total exhaustion to the point of being uncomfortable. All while drinking alcohol in mostly silence. Talking is discouraged, like a library.
I hate this idea, but that means I think it would be extremely popular with normies. Because I’m a weirdo.

Irish silent rave.
