So I was at the beach in a truck with some girl that supposably helped me out in some other dream, yet I have no idea who she is. Anyway, we pull up near the water, and there was a lot of people, she says "This is good, stop here.", so I do but instead of changing to park for the car, I put it in drive again... somehow? I was scared and starting running people over and turned and went the other way, people shouted at me :

"Dude, you just ran my hand over, it fell off."

"Holy shit dude, you just ran the fuck out of that guys head over.."

"Your going to be locked up for life."

At this point, I get scared into lucidity and get out of the truck and look around me, I see a dead corpse floating the water, a guys hand fallen off, and some guys head was smashed into the sand. After seeing this I couldn't stabilize and fell out of the dream.
