Jerk awake minutes after falling asleep

Anonymous
For the past week or so, maybe more, I've been falling asleep and then moments (or minutes?) later I kind of jerk awake, almost startled.
There is no noise, it is always quiet and peaceful in the house do I can't figure out why this is happening.
I think I've experienced this before, but it's been once in a blue moon rather than every single night!
Anyone else go through this? Once awake it takes me a little while to fall back asleep, and then I'm fine the rest if the night and sleep through.

Sorta like a whole-body muscle twitch/spasm, right?

DH does this every once in awhile and it annoys me (he sleeps right through it). I think it has something to do with your muscles relaxing and constrict/contract a bit in doing so.

It happens to me almost every night and always has. Same for DH. Hell, same for my dog even.

OP here. Interesting. I did a goofle search and it is quite common, but I've never experienced it like this.
I read that it can be exacerbated by stress or anxiety, and I'm definitely more wound-up than usual so I get that has something to do with it.

I do this almost every night and have for a long time. No idea why.

You're annoyed by it? You know it's involuntary right?

It's so you don't fall out of the tree, OP.

It's called a hypnic jerk

I've done it my whole life. Never correlated it with stress or anything. I just figured it's one of those dumb things that bodies do sometimes.

That's why they call it "falling" asleep.

I get his but often just body parts not whole body. I find it's exacerbated by being overtired etc

Hypnick jerk and it was explained to me by a neurologist that it's the brain's shift from non-REM into REM. Mine do have the "falling" down a stair component. That way I always know I'm "falling" asleep when that happens. It's very normal, although there is also this for you to explore. http://en.wikipedia.org/wiki/Periodic_limb_movement_disorder
