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.
Technically I can relate to the dreams thing but for completely different reasons. Dreams on their own are fine to talk about IMO (most famously as a conversation starter and I even help host a group set up for them), but once in a while you’ll find literal dream preachers (my first BF was one of these, coming to the meal table was a chore), and I might ask something like “will this be on the test”. It’s not some kryptonite, it’s just dull-ish for a lack of a better word, though I’m not singling it out either.
Yeah, I studied psychology and I like to play Jung a bit when people feel the need to tell me about a dream they had, which in theory is by definition something their unconscious needs them to be aware of. So I ask what they think about it, what they felt at different points, etc. Usually the dream is either absolutely illegible, or unsurprisingly obvious. No in-between.
Just one dream at a time? I thought comparing/contrasting multiple dreams was part and parcel to that process.
