Hypnic Jerk?

For some reason, usually about 2-3 times a month, I'll be laying down like normal, trying to sleep, Usually sitting and watching my mind wander, not literally watch it, since I absolutely suck when it comes to HI. But I'll be laying there, thinking about random stuff, then I'll usually get this sudden feeling like I'm about to get hit by a car, or get punched, something like that. I then try to dodge and my whole body jumps, then I usually am fully awake after this. This isn't a dream thing, it seems to happen at that stage right before you lose conciousness and fall asleep. I don't know what this is, I figured it was a Hypnic Jerk, since the symptoms match, any ideas? Thanks for reading:)

That's exactly what it is. Good guess. :)

Yes, I love having hypnic jerks in school. :eek:

HAHA It's quite an experience, because it happens to everyone and it's even more fun to watch some one else have one. ROFL


Mine is always a falling feeling whether I fall of the edge of the earth or down some stairs, I always am in a VIVID dream by the time that happens. It always wakes me up though.. :embarrassed:

Thats what that is! I've always wondered what it was when I'd be in school falling asleep, and all of a sudden I'd just jerk for no reason

Thanks for the help! This happens to me all the time, but not in school, unlike you guys, I actually stay awake during school :D, actually I have fallen asleep one time in school, but usually I can't sleep in school.

Lol, I whenever I jerk it's because I thought I just slipped on ice. It's cool though, cause I just keep laying there and fall into a dream.

Omg u just reminded me of an expierence i had i had literally just gone in a dream state then all of a sudden i see a high speed car come straight for me and of course i jump out the way and i hit my head in rl :S i do this alot lol

With me, it's always either my leg suddenly spasms (typically left thigh), or I'm half dreaming/half dozing and I suddenly realize that gravity is at a right angle to what it should be. The weirdest part is that I occasionally try to twist and lnd on my feet, which occasionaly throws me off the bed/couch/across the floor.:shock:

I've had hypnogogic jerks from time to time ever since I was a little kid. Sometimes with imagery and sometimes without. With a lot of the ones I experienced when I was younger, I'd imagine that I was running really fast, and suddenly trip over something really hard, and I'd jerk awake really fast, thinking I was about to fall down on my face, haha. In some other ones I'd think I was in a crowd of people and somebody would suddenly run up to grab or attack me.

Hypnic jerks help me sometimes when I try to WILD, when I try to WILD I sometimes nearly slip away into normal sleep. The hypnic jerks get me back.
