Interesting. I've visualized the numbers 1-100 as a specific path of tiles, sort of like a hopscotch grid, since i was like 3 or 4. 1-20 is a straight path rising in elevation, descending back to the ground from 10-20. At 20 the path turns right until 40, at which point it turns left and goes up from 40-100. At the boundary between 100 and 101 there's a "gate", sort of like a skylight. 100-200 takes a totally different path than 1-100. Pretty weird, i have no idea why my mind does this.
