I'm not an expert, but it seems like the REM stage wouldn't occur if you were sleeping. That'd just be really uncomfortable. The thing with your eyes flickering rapidly is why it's called "rapid eye movement" (REM). It happens every time you sleep, but most people never experience it, because they are asleep. I don't know if you can experience it during paralysis, but perhaps yo ucan.
