What do you call it when "a ghost passes through you"?

[nhmllr]

There's this phenomenon that occurs to some people a handful of times in their life. My friends and I describe it as "a ghost passing through you."

Here's what happens: You're having a seemingly regular day, standing on your feet, and then all of a sudden, without warning, you get weird, small, quick spasms that last about one second, maybe less. Your knees might become weak and your could collapse a little, but rarely fall over. It's always kinda funny to watch it happen to someone else.

I can remember this happening to me three times, it could be more. I don't have any medical conditions, ADD, Epilepsy, etc. There doesn't seem to be a pattern as to when it happens. I know it can happen to other people and not just me.

What is this ACTUALLY called? What causes it?

Maybe you guys can shed some light on it. Thanks!

Muscle fatigue?

Can it be spontaneous? I don't remember being tired when it happened. It just felt like all of a sudden my knees weren't supporting me and I couldn't do anything.

There have been times in my life when I have exercised a lot and experienced similar sensations. One time after some relatively intense exercise I walked my dog, and on the street I had this awful feeling that I was going to collapse right on the street. The feeling grew and dissipated over a period of about 30 seconds, but I barely held out and I felt fine afterwards.

The thing about the sensation I'm describing is that it's seemingly random and unannounced.

It seems to me to be more neurological than anything, because arms flail a little too, and you shudder. It's not so much fatigue as loss of control.

It doesn't really matter, I'm just curious.
