I've been afflicted with sleep paralysis since I was a kid. As a kid, it was never anything bad, I'd panic as I tried to wake myself and breath.
In my mid twenties it went dark. I had an episode in the middle of the night with a demon. I woke up attempting to throw a punch at this entity that was pure evil. I wanted them out of my house. Over the years I had a few other creepy/dark encounters. They were rare and only happened maybe once a year.
That was the case for years, until this winter. I had three nights in a row of very evil episodes with these dark entities. I was at my wits end. I prayed. I prayed ephesians 6:10-18. Asked the lord to help me fight and defeat them.
It stopped. That very night I had the best night's sleep that I've had in a long time.
The lord will protect you, just ask.
Saying Jesus name, calling out to Jesus usually stops that crap in it's tracks. I've also experienced this. Been many years since it happened now that i pray more, study more, and am firm in my belief in Christ.
"This is JESUS' house, be ye gone from me."
