"Many years ago, my husband woke me up one night, gasping for breath and choking. HE WAS WIDE AWAKE. He kept saying, "get it off, get it off, it's choking me."
Look up the 'Old Hag' or 'Succubus' phenomenon. It's a waking dream you nit. It's also known as hypnagogic/sleep paralysis. As others have said, it could also be sleep apnea but since he kept saying, 'get it off, get it off, it's choking me' I'll stick with sleep paralysis.
"We had, by that time, become haltingly proficient in "binding" demons because of the necessity foisted on us over the past year through various circumstances."
Yeah, sure. Strange that I never have any problems with demons, goblins, ghosties or other supernatural things pestering me. Then again, I don't believe in them. Funny how they have no power to interfere with you at all once you stop believing in them.
"Again, Praise Jesus, I was aware enough to immediately call on His name and watch Jesus (not Him, but the release) stop the attack."
All your hollering and carrying on probably woke your husband up completely thereby bringing an end to the experience. Your Jesus did nothing since it's a completely normal physiological condition to begin with that ended due to your ranting and raving waking your husband fully.
