Dying Black Bird

A couple of nights ago, I had a dream I was in my grandparents backyard. All of a sudden I giant, black, cartoonish bird (maybe a crow or raven) flies down above my head. It had crazy looking eyes..it was swirls. Anyway, it stops dead in tracks a couple of feet ahead of me in mid-air. Then it proceeds to flying backwards in a straight line towards my grandparents garage, but ends up lifeless in the backyard with his eyes open. I just stood their and stared because of it's cartoon looking body. I ended up walking on my grandparents porch and turn around, and the bird flew away. Kinda weird, but got me scared.
