What works have “spicy banana syndrome”?
You probably don’t know what that is, so I’ll explain it to you:
If one character in a work thinks bananas are spicy, they are allergic to bananas. But if *every* character thinks bananas are spicy, the *author* is allergic to bananas.
TL;DR: The creator of a work thinks something they have/experience which is rare is common or even universal
