Most of my nightmares are generally the same: a tall older serial killer/rapist chasing me and then my legs give out from running and I try to scream, but I can't and I wake up before anything bad happens.

I have this one recurring dream though were my school is filled with burning crosses and if I get too close to one, my heart gets RIPPED out of my body and I die only to come back to life and try to get past them again.
