the most asexual/aromatic thing that's happened to me was after watching Much Ado About Nothing (1993), I had a stress dream where I was inside the story of the film. This lady I didn't know kept on insisting that she was attracted to me, and that I was attracted to her, and I should go with her.
It then spiraled into me trying to tell her I wasn't interested in anyone for that matter. Resulting in her having a breakdown, which I didn't know how to handle. I tried helping, but in true stress dream fashion, it just got worse. Then random characters came up to help but started yelling at me for rejecting her.
I woke up thinking "well, that proves it" and never want to watch that film ever again.
