I think there are two types of people who describe dreams: 1) Those who are essentially saying, “Listen to this absurdity, isn’t it hilarious/weird?” and 2) those who are trying to pick up insights and think their dreams mean something. It’s the difference between reading a fantasy novel that is all about characters, world building, and a cool story, and a fantasy novel where the author is trying to make some point about the real world and how something should or should not be.
I definitely fall in line with OP’s sentiments about that second category.
Excluding the obvious ones such as politics, what topics can't you stand listening to people talk about?
For me it’s detailed describtions about people’s dreams....
