[Question] Which things were you surprised to learn are not metaphors?

People with aphantasia typically think that when someone says to “picture X in your mind”, they’re being entirely metaphorical. If you don’t have a mind’s eye, that’s a super reasonable thing to think, but it turns out that you’d be wrong!

In that spirit, I recently discovered that many expressions about “feelings in your body” are not metaphorical. Sometimes, people literally feel a lump in their throat when they feel sad, or literally feel like their head is hot (“hot-headed”) when they’re angry.

It seems pretty likely to me that there are other non-metaphors that I currently think are metaphors, and likewise for other people here. So: what are some things that you thought were metaphors, that you later discovered were not metaphors?
