Dreams definition: snakes fighting?

I had a dream last night that I went round someones house and there was a rattlesnake lashing out at a smaller snake and it kept biting its eyes and covering it in venom then it turned on me and bit me on the leg and i had this really bad pain and in my dream my leg went all red and sore then it went on to another weird dream, but what does it mean because i am intriuged.
