As an introvert, what are you even supposed to do at "clubs"? Besides having your eardrums damaged
It's why I never liked clubs I prefer small bars where you can talk to people. I've been in Berlin for 16 years now and there are plenty of those bars around. Even now that I no longer drink alcohol, I still enjoy going there.
But I never saw the point of the club scene here. I don't actually mind some of the music and there are some nice Berghain playlists on Spotify that I listen to occasionally. I just never felt any need to actually go there. Just not my thing. My impression of talking to people that do go to these things is that it's a lot about just being seen there or being able to brag about having been there. And then there are of course a lot of people that just go nuts and do that for the whole weekend while taking lots of pills. Also not my thing. But live and let live as far as I'm concerned.
Berghain particularly doesn't just let everybody in. People queue for ages and can then get told off for looking wrong or whatever. Elon Musk famously got an access denied there once. Not cool enough. Which I find hilarious. But the prospect of being vetted like that is a definite turn off for me. I just don't like that kind of snobbishness.
