When I was a kid, everyone used to say that if you fall off say a cliff in your dream, but don't wake up before you hit the floor, you die in your sleep.
Well recently I've had a dream where I've fell out of a plane, but in the dream I hit the ground before I woke up and guess what........... I'M NOT DEAD!!!
All that happened was I felt my legs go up into my body and heard every bone in my body break, then when I did wake up I was shit scared to move in case I was paralysed.
