No, I don't get far enough into sleep for that - it happens right at the point of dozing off. I know what your talking about and do occasionally get those kind as well. I will dream something like I'm walking down a sidewalk and suddenly the next step isn't there and I jerk awake. I usually get this if I fall asleep sitting vs laying, etc.
