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.
