It's common (normal?) to perceive things more severe/serious when they affect us personally.

My experiences have been pretty textbook, and I never really thought—much less worried—much about them before now. On the occasions it happens, when I'm dropping off to sleep (doesn't matter if I'm prone or sitting), I get a sensation of falling that causes me to jerk awake. Sometimes I grab at something to try to catch myself. I think it's only natural to get a little shot of adrenaline when falling. Sometimes there's a feeling of nausea; I don't know if that's a response to the adrenaline or some other brain chemistry, or just tied to the fight or flight response to the falling sensation. This can happen several times in succession. When I'm sitting up (falling asleep in front of the tube) I get up and go to bed. When I'm in bed, it's often tied to my apnea, so I make sure I get comfortable & adjust the cpap mask. If I have to, I'll get up for 20 min - an hour.

I watched several other videos of people who either said they were having myoclonic seizures or asking if they were. I've got no expertise/training in this, but in the majority of the videos I watched, I couldn't see anything different than the typical jerking/movement one does when (falling) asleep.

I'm not saying this is what's going on with you, but I'd like you to think about/consider it, then decide for yourself (if you haven't already). Most of the folks who find their way here (myself included) are understandably freaked out by whatever is going wrong, but some also become obsessed to the point of their fear/obsession becoming worse than the underlying cause/symptoms. It's difficult to think about things logically/rationally when you can't get enough good sleep to balance/normalize brain chemistry.

The neuros I've seen have not been for sleep issues, though I have had a sleep study; I have obstructive apnea and use a cpap machine. I also get insomnia quite often. The neuros I've seen have been for chronic headaches/migraines, and later on for peripheral neuropathy.
