while I'm not too keen about the interpretation of dreams, and am not heavily into reading of signs, my brother had told me a while ago that sometimes dreams, just before we wake up, are telling us something.
Having had one such experience, I do believe that there is an element of truth in this - at least one can become aware of some potential situation, and take the steps necessary to deal with the situation - cope/counter/do whatever is needed, so that the situation can be turned around...
