Interesting! I've always experienced this.
For me, numbers are ordered in a very neat line; 1 2 3 4 5 6... etc, with size being uniform up to 20. 20 ~ 30 is more "squeezed together", and the rest of the tens aren't very clear unless I think about them, in which case a group of 10 numbers sort of fill up on a horizontal line in my "mind's eye". Once it gets up to 100, the digits become about two-three times as large. Here, I can for some reason see many more numbers than usual - I can clearly see, for instance, 270 ~ 310, but not 40 ~ 70.
1000 is for some reason smaller again, and it pretty much goes on except in a more "zoomed out" fashion. Once I get up to about a million, I only see 1, 2, 3, 4, 5, etc up to 10, and then there's about as much space between 1 and 10 as between 10 and 100 (million). I have a roughly similar view of billions, but not a very well developed sense of trillions or quadrillions for most likely obvious reasons.
Now, for weekdays, they're ordered a similar way. They're basically ordered on a horizontal line, and I see them as text; Usually mon tue wed thur fri SAT SUN. For some reason, Saturday and Sunday are always larger and more spaced out. A funny thing is that while I don't *see* colors in the image, I still perceive the weekdays as having colors; monday is blue, tuesday is yellow, orange is orange-beige, thursday is brown, friday is green, saturday is yellow, sunday is white.
Let's see... The year. This one is odd. My year goes counter-clockwise in a skewed wheel (the upper part is much larger), starting with January at 6, February at 5, March at 4, April at 3:30, May at 3, June at 2, July at 1, August at 12 (My birthday is in August, probably why), etc until December, which is at 7. They're basically "written" along the "clock" (not an actual clock, just the best way I could describe it) and I can zoom into see the dates ordered up next to each other, usually written above the weekdays, though I don't have a very good sense of dates, to be quite honest. A funny thing is that, and I've never thought of this before, the numbers are actually ordered right-to-left in august and second half of July and they continue this way until December.
Lesse... What more... Years. They're just ordered in a regular fashion like the numbers. Though the 2000's are more "elevated" (like, towards me) than the rest.
I also see words that I hear in front of me. Oh yeah, and when I hear music (voices too, I think) I see it in front of me, kind of like a "chart". If it's singing involved it's more like a jagged line, if it's something like a piano piece I usually see a note sheet in front of me. I also have a tendency to see two hands playing piano whenever I hear piano music, not sure if that's related or just an association.
Oh yeah, the alphabeth.
A B C D E F G H
I J K L M N
After that, it gets complicated. They kind of show up in pairs, O P, Q R, S T, U V, on a vertical line.
then X Y Z Å Ä Ö neatly ordered like the first two lines. I remember that I had much harder learning the letters after N, and I still have to think an extra moment for most of the ones between N and Z; it's not obvious to me that R is before T, for instance.
