Dream of girlfriend

I was in a car with my ex- girlfriend and I faintly remember driving to the hospital with the possibility of her being pregnant. For some reason, we are in the car I lean over and she shoots me in the stomach with five nails. After that, I has shot in the head but I didn't bleed or feel any pain. We go into the hospital and she gets separated from me. After a while, I pull one of the nails out of my stomach and I vomit a white, foamy substance. Any insight on what this means?
