In the dream this guy is an actor making a tv commercial and he is sitting on the ground in front of a short fence and he has a big head of black hair. There are these two big black and white cows on the other side of the fence and they are leaning over the fence and licking his hair.
They had put something on his hair to get the cows to do this.
that's all there is to this dream. I cant tell you what product that the commercial was trying to sell.
