Sleep paralysis

So, let's talk about something more serious but still not too serious, and popular enough (I hope) to attract some interesting responses, and who knows, maybe first hand experiences.

Sleep paralysis is a phenomenon in which an individual, either during falling asleep or awakening, briefly experiences an inability to move, speak, or react. It is sometimes accompanied by frightening hallucinations to which one is unable to react due to paralysis and perceived physical experiences... - Wikipedia.

Some scientists have proposed sleep paralysis as an explanation for reports of ghost, parasites, alien visits, demons or demonic possession, alien abduction experiences, the Night Hag and shadow people haunting... - Also Wikipedia.

I've clicked on articles about Night Hag and Shadow person and since I live alone, no sleep for me tonight :(

Jokes aside, I've experienced sleep paralysis at least once. Woke up in the middle of the night, couldn't breathe, my throat and lungs were frozen, and electric current was shaking my entire upper body... I felt like I'm gonna die... like my tongue is turning to dust... still, somehow managed to start breathing through my nose when I remembered that can be done too.

So... your turn. Tell us what you've lived through.
