I had a dream last night that I was in the car with my sister and mom, when they started to fall asleep, my mom was driving, and I felt like I couldn't do anything, and I started drifting asleep to, thinking it wouldn't hurt anything, and the next thing i knew, we had wrecked, our car flipping several times, but landed back on it's wheels, and we were all okay, just cuts and bruises but I had hurt my stomach, and I stummbled out of the car, and puked up a bunch of blood. Then I woke up, feeling nauseous, and all day today, i've felt sick to my stomach.

(I apologise to those people who read this after using safe(r) mode in an attempt to stay out of the weird part of this site.)
This happens to me every now and then as well so I'd say it's quite normal. Sometimes I can actually... feel things, in my dreams as in if i was to get a cut, I'd actually feel the pain.
Strange eh?
