I only had to think for just a few seconds and it came to me. Then I realized, "Yes, that was a significant dream." I got up and wrote it down and then went back to bed. I remember feeling like I needed to pay attention to the horses - they were the most important part about the dream.
While searching online about some of the symbols in my dream I read that horses in dreams can sometimes have prophetic meaning. I've posted the dream below along with what I think it possibly means. I'd love to hear any thoughts about it.
