bad dreams

Last night I had some terrible bad dreams. I dreamt that I was in some kind of field and that I was running. I dont know where I was running to or who I was running from, but I do remember that some snakes were chasing me along the way. I remember that I would just jump them over and keep running. It was a very weird dream. I remember some time ago that someone told me that dreaming with snakes is like having a spiritual battle, that the snakes represent evil. I really dont know if thats true or not, but if it is then that means I was winning this battle since I was not being hurt by them. What a weird dream I had and how I wish I could interpret it.
