For me it’s detailed describtions about people’s dreams.
Not only doesn’t your story make any sense, but you’re also telling me about something that didn’t even happen. It’s kind of like telling about an event, and then ending the story by saying you just made it all up, except with dreams you begin by telling it’s all made up. I’m already not interested before you even started.
People talking about what alcohol they like. I don’t drink so it’s just boring to me and I can’t relate whatsoever.
That sort of talk disappears when you get older. People might briefly chat about their favorite whiskey or whatever, but they’re not having whole-ass conversations on the topic.
