This one scares the shit out of me!

I hate when that happens! Seriously I'm havin a peaceful dream about whatever,then suddenly "FAJDKDWRYFHKBASG"!!

I mentioned this to my dad and I kind of confused him about it. So I asked him "hasn't this ever happened to you before?" and he was like "No? Why would it?"

I am a part of that 30%

It's funny when it happens when you're on the verge of sleep, just barely awake enough to realize that it happens and in that comfortable haze of sleep you think to yourself "heh I'm weird".

This has happened to me several times. I never knew the reason until now

I have this, sleep paralysis (your mind is awake but you CAN'T MOVE), and I sleep walk.

I'm that percent that feels it maybe every other week

I heard somewhere that it happens when your blood pressure drops low your brain thinks it's about to stop. To try to keep the heart going it sends a "shock" to your muscles causing you to wake up suddenly.

I've never experienced. Sometimes I feel like the room is spinning, but never a falling sensation.

I'd be in bed, going over my day, then I dream I trip and my whole leg twitches and I wake up

Ugh! At least I know I am not alone with this :p

i used to have something like that when i was younger but id fall asleep instead of wake up, like the falling feeling would come then id fall asleep

this happens because if your heart rate slows down while sleeping so much that your brain thinks that you are going to die so it plays the image of you falling to wake you up.
