Discussion Passing out by holding

Is it possible to pass out by holding your breath? How painful it's it? How does it feel? Do you fill your lungs completely or empty it because you do it?

It's hard to do by holding your breath because your brain/body may force you to take a big gulp of air anyway when it senses you are in danger. However hyperventilating is more possible to do and pass out from

I read somewhere that you can do it.
You will pass out, and as soon as you are unconscious you will automatically start breathing again. I don't know after how much you'd wake up.
So it's kinda pointless, unless you do that in a body of water.
