I've seen stuff like this if I Google a part of a song lyric, movie quote, or something I remember out of a book. What I'm looking for is the exact quote and maybe some more context. Sometimes the AI overview treats it like I want to say the quotation in the first person, and responds to it in a somewhat personal tone.
It's some combination of funny and irritating. Sometimes I wonder if they'll draw some wrong conclusions about me and try to sell me ads based on it.
