A few weeks back I was hanging out at the guitar player's place and we were playing some of the cover songs in our setlist for fun. I didn't bring my bass so I used theirs. Problem is that guitar player is left-handed and I had to play the bass upside down (E at the bottom and G at the top). Fortunately it's a semi-hollow and the body shape is pretty symmetric, so it didn't felt weird playing that way.
For the majority of the songs I was able to quickly mirror the notes to the leftie fretboard and play them alright - the basslines are not that difficult after all. But some fills I was struggling because I realized I had been playing them through muscle memory, while having no clear idea what the notes are and where they are on the fretboard. During practice I must have just built the muscle memory and have been on autopilot since.
This provided a whole new perspective in my playing, because the difference between mindful and mindless playing became very clear to me. I think in the future when I'm learning new songs I'll definitely keep that in mind, and probably need to re-learn some of the songs that I already know.

you're relating the "upside-down" experience (i've done it a few times: same as your experience, more or less), and we've all probably had the experience of playing our own axes "backward" (plucking/"fretting" in reverse).
