Hi Kevin.

I sure can relate to the "getting lost" thing with playing guitar.

Your post made me think about muscle memory working with the ability to concentrate on different things at the same time in a different way. In particular, motorcycle and guitar.

Riding a bike involves lots of muscle memory AND concentration. I remember first learning to ride. Clutch, throttle, shift, brake, balance, lean....all have to work together....AND you still have to pay attention to everything that's around you. Eventually, the muscle memory stuff became almost automatic, and required less "thinking and concentration", right?

I've found it similar with guitar and playing along with music or others. I have to learn something solo, to the point it's kinds coming without thinking about every little bit of it, before I can play along with anything.
