Knocked out?

I was drunk one time and have an argument, to tell a long story short someone applied pressure to the final of my neck and i be knocked out by it, i woke up and it happen again, and then again, untill i get away. i wondered if anyone has experienced this past and how does it happen?, and is it terrifying?Knocked out?
yes, it could have be dangerous.
You passed out because necessarily they cut the blood and nerve supply to the fund of your neck, a exceedingly silly thing to do and it usually pinch about 3 second for somone to go by out because of this.
If done for a long time, death can come about.
It's very unsafe, you should have have him charged with assault later he may have thought twice on the subsequent occasion.
YES IT IS DONT MESS WITH THINGS U DONT UNDERSTAND
Happened to me,...contained by three seconds i be on the floor dreaming ,...
In my case be because I didnt believe it`s possible and insisted to see how it feels as i never passed out back...
Nothing bad happen to me because of that, but I`m not sure i`d let it ensue again.
The answerers above explained you correct the cause...
Never hear of this happening as an assault though,..
