To see a cow in your dream symbolizes your passive and docile nature. You obey others without question. Alternatively, a cow represents maternal instincts or the desire to be cared for. For some cultures, the cow represents divine qualities of fertility, nourishment and motherhood. I got this answer off of this link- http://www.dreammoods.com/dreamthemes/animals.htm That is what it means to see a cow in your dreams, but I am not sure what it means that its attacking you. But, this is probably your closest answer to all of it. I hope this helped. And, if you dream of anything wacky again, I just go on Google and search the differnent aspects of my dream and put them together.
