It’s okay to admit: You may never have heard of the eerie, masquerade-style Sleep No More before watching Gossip Girl on Monday night.

Don’t worry, we’re here for you! Here’s your handy little guide to the real-world references and happenings you might have missed from Gossip Girl Season 5, Episode 7: “The Big Sleep No More.”

If Gossip Girl is your guide to cultural goings-on, you could do worse this week. Sleep No More is a real Off-Broadway show that's been running for a few months now and it’s pretty awesome!

Believe it or not, Sleep No More is even more eerie and beautiful than it appeared on TV. It's also exhausting, nearly pitch black, and if you tried to kiss someone in those long-nose masks you'd probably take out an eye. But it's totally worth checking out, even if your chances of Nate (Chace Crawford)-snogging are much lower in the real thing.

Well, lookee here: Bergdorf really does have a restaurant inside. Max (Brian J. Smith) should have pushed for S to follow through on her lunch offer — $32 entrees might not come along every day for a poverty-stricken itinerant chef. But if you want to follow the path not taken (by Max), BG is at 58th Street and 5th Avenue on the seventh floor.
