Whit was secretly a part of Inception.
I guess I.. wouldn't really know. xD I don't have jolt-you-awake dreams very often at all, and any other way, it's kinda like knowing if you're snoring while you sleep.
It works the opposite way for sure though - sometimes in my dreams, I'll find myself unable to move. I've always figured this is because I can't move much in reality either.
And when I was a kid, I had a lot of falling dreams.. Prob'ly because I fell off the bed every night. xD
