Do you ever have visual experiences in dreams? It's like that, but you're awake.
I thought the exercise thing (like runner's high, feeling pumped, etc) were all metaphors, but I was surprised to learn other people actually felt good after exercise. Whatever it is, I'm missing the mechanics, and exercise is pure duty (so I try to get it doing other things I enjoy, such as walking my dog and chasing children around).
I've had the opposite experience with music, when I said a harmony made me feel shivers and the other person didn't realise I was being literal.
Music pitch (high/low); the metaphor is so embedded in me from pre-memory days that I struggled to accept that it's just a convention. Many other binaries (such as long/short) would work just as well.
