I can only comment on the beginning of your dream:
You are at home. Typically this means your body. You are in the bedroom. I view this as being an intimate space, rather private. You are sleeping. I think this dream is trying to tell you to wake-up. Although the noise does the trick of getting you out of bed, it doesn't accomplish the waking part. In the dream you repeatedly curse yell rant and rave. It does nothing. You do it over and over despite the fact that it gets no result.
Not sure about the black dude. Since the first attempt with the noise wasn't enough, maybe a more drastic approach was needed? Something to really get your attention?
Ok black could indicate negativity. Do you view men in a negative light? I'm wondering if somehow a lot of YOUR energy is being tied up negatively. Perhaps the "rape" is an attempt to join with that energy? Not sure what it's worth, but that's my take on your dream
