Well first of all, good job for describing some background, things you were feeling, etc. Was there anything you encountered at the time that was "devil-esque?" I know that for me, I will dream about things that I just saw in the past few days. I don't know you, so take everything I say lightly. You said you were running from a person who was trying to kill you right? That may be a reflection of something that happened in your life that was traumatic. Is/Was there a person in your life who hurt you deeply? When you turned into the devil and didn't feel evil, it might mean that you take the blame for doing something "wrong" but ultimately you didn't do anything wrong. Realizing the truth that it was a dream is exhilarating, and that is probably what gave you the boost to get out of being trapped. When we realize the truth, it is freeing. Ask yourself what is true about any of that and dig deeper within yourself. Do you have any questions about what I said? Let me know! I hope you can find out the true meaning of your dream.
