Dreams about the devil usually are telling of another side of yourself. A destructive side. Always pay close attention to the dream as its hints may tell of what part of yourself is getting too self destructive. Most times a suttle answer of what to do should also be in the dream one way or another.
Something terrible is about to happen in your life. It could be an accident or a run of very bad luck. But when a devil`s curse is dreamed about it is not a good sign. There are evil forces at work and someone has got it in for you.
