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.
I don’t know if this is unpopular or not, but I really don’t like hearing about folks’ medical history. Like yes, I know you have anxiety/diabetes/whatever because you tell me every single time I see you. I, too, have a condition that requires me to take multiple pills everyday for my whole life, but you’d never know it bc I don’t make it my identity. I’d rather not, and I’d rather not others who aren’t facing death do it. On some cases I guess it speaks to the status of mental health care in my country since it almost seems like a cry for help that I just cannot answer.
