Dream of cow, mother, person, screaming, child

I dreamed of a cow and her calf. They were in a stable with many other cows. The stable was dirty, the floor was covered with mud and dirty hay. They were rather isolated from the rest of the cows, but not in a strange way (it looked like that was the place they should be). The mother cow was nursing her calf. She was a large cow, kind of fat. The cow turns slowly her head and looks at me, I wasn't there in person though (I was like a cameramen) and suddenly the upper side of her body, directly up from the "nursing post", explodes, spraying a liquid out of the hole (it was a little one, and the liquid was colored faint yellow with black mixed in it, but it was realistic, it looked like rotten milk). Directly after the explosion, the cow starts screaming and jumping. First she makes a kick gesture and then jumps over her calf, who stands motionless, and starts running trough the stable's alley, screaming and, for a second, it seemed to me like she changes form, becoming kind of rectangular with the head fused with the body. While she runs she has the tongue sticking out of her mouth and keeps staring at me with one eye, like horses do sometimes. The cows, including mother and child, where white with black spots, although, when changing appearance, the mother turned all black (but the tummy and the rest of the lower body remained white). The cows were dirty in color, not bright white. I'm male 35 years old. Hope I gave enough information ;)
