Dream Premonitions Options

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?

This is very interesting to me because premonitions in dreams are the most common "provable" magick i seem to have. Once i started keeping a dream journal weird de ja vu moments and sometimes actual things that happened in dreams happen in real life. Unfortunately, most of what I see in my dreams that happens in real life is a very abstract thing, like putting on a sock in a chair while the door to my garage was open and then having a vivid flashback to where that happened in a dream, almost like i had scene it as a picture rather than a full vision i guess.
