> I think a reasonable explanation is they are also resistant to whatever the chemical the brain uses that causes sleep induced loss of consciousness to the point they are more prone to sleep paralysis.
I cant rule out your explanation, but I personally in favor of another one. It is not a supression of consciousness doesn't work, it is the clearing blood from whatever the chemical that stops propagating signals to muscles. When everything works good you are relieved of paralisys at the same time your consciousness wakes up. I never experienced sleep paralisys, but when I wake up suddenly and try to move instantly I can sometime feel a fleeting sensation of it. I never gave it a second thought before I learned about sleep paralysis.
