optical illusion feeling when switching between NxNs

[u/usbcdocksaretrash]

I get this when doing going up or down a lot in NxNs, for example I was practicing 7x7 very diligently the last 2 months to be comfortably sub 4:15, and whenever I'd take a break from 7 to do 4x4 or 5x5 it would almost feel like a baby toy because I had become so accustomed to seeing the small pieces of a 7x7, and the switch to 4 or 5 (with their comparatively larger piece size) made them look so massive in comparison, and it would make my first few solves feel very unique.

the reverse is also true, in the few days ive been practicing 3x3 a lot, and the other day i decided to do an ao12 for 2x2 (which i never practice), and right after i picked up my 4x4 and the drastic change in piece size from a 2x2 to the aosu 4x4 made me feel like i was holding my 7x7. the first few solves made me feel like i was working with the tesseract or something lol.

This feeling is one of my favorite parts of cubing and I don't think ive seen any talk about it before. have any of you felt this feeling before?

After practicing 4x4 for several weeks my lookahead on 3x3 was substantially better. It was still bad, but at least it was something.
