I don't think we've ever declared any trope "real life only". There's certainly nothing on that trope that says it can't have a "fictional/in-universe" section as well as a "Real Life" section -- IIRC we have more than a few tropes with examples divvied up like that. I'd say do it that way -- demote the existing example sections to "===" headers under a "== Real Life ==" heading and create a new "== Fictional ==" section under which to put in-universe examples.
