But your number descriptions? Completely unintuitive. All those orders that you differentiate as "boring" or "clever" or "cold" or "heavy"... I don't see that at all, and I'm pretty sure the vast majority of people would not see it either. The orders are just random and applying concepts like "cold" or "heavy" to a string of numbers makes no sense at all to me. That you just naturally feel those descriptions for orders is really neat... and it really probably is a form of synesthesia, even though you didn't realize it. And that's cool!
The orders aren't random, I spent like 30 minutes arranging and re-arranging the numbers so that they would be describable with words as much as possible. They were a result of my own inspiration, and that's why it was easy for me to describe them. But this number: 6415131409310 (I currently see it in a juice can on my table), I can't describe the impression I have, because the number isn't designed to have a clear atmosphere on it.
It's the same thing with music (obviously, because music after all is just numbers): this song, for example, is sad.
But the very fact that those number arrangements aren't random to you is just more evidence, because they are ransom to most people. The idea that a sequence of numbers could even have an atmosphere is a foreign concept.
You might not find it extraordinary because it's just normal to you, but it isn't to most people.
