I don't know about the voices deal, but the dream part is explainable. Sometimes you dream about everyday things that you are used to seeing in ordinary life, but when you dream about it and it happens you notice it a lot more. It doesn't necessarily mean your "dreaming the future", rather, you are dreaming about things that happen all the time without you noticing them, but now that you have dreamt about it, you do notice it. I hope that makes some sort of sense.
