Today, as an adult, I've learned that I have "temporary space synesthesia". If I tell the truth I'm not surprised, I always wondered if other people saw the numbers, letters, dates (days, weeks, months, years, seasons...), musical notes... like me. Now i know they do not, and that is something that happens to many people.
Now I understand many things, but I also do thousands of questions.
You can find information on the web if you are curious, maybe some of you are also synesthetes
