This might belong in Dream Works, but as my questions that go with this are about the prophetic side, I've posted this here.

Last night I had many dreams, not a one of which was not a premonition. I saw my future, my father's future, an ill fate for my dog, my friend's alcoholism taking a turn for the worst, and an old crush who I still talk to excelling in her chosen career.

My questions are:
Are these things just what is most likely at this point in time?
Would my fate, as I dreamed of it, be taking into account the fact that I dreamed of it?
Being as these dreams all came together, would changing one of them likely change them all?
