Dream of

OK this is really weird. I have frequent dreams about brown bears, but the latest one I don't understand. As usual, the setting is in the field across the alley of where I grew up. I saw children playing in the field and then a mother brown bear & her cub. She leaves the cub (next to the field) & comes into our side yard, where a reddish tan cow is standing with its tail end facing me & the bear. This is where it gets weird. The bear goes up to the cow and sniffs it rear end & I can hear it. Then, I know the cow is pregnant. As the bear then reaches its paw inside & rips the fetus out I turn away because I can't 'bear' to watch. I hear it slam the fetus on the ground. What ever can this sick dream mean? This may seem untrue but I assure you this was my dream. It really disturbs me.
