“Sleep apnea?”
No,,, something far more complicated. I am asleep and awake at the same time. Falling asleep is very difficult. REM is a mess, as I’m also awake while it’s going on. My doc thinks that I have many more connections between my right half and my left half. I am a musician who never plays the same thing twice. Good and bad!
I value improvisation over the same thing every time. For example, my favorite band plays different leads in their songs for every tour.
But I’ve never heard of asleep and awake at the same time. Have you gone for an MRI and/or sleep study?
