The Dreams of a Trapped Mind

So, I've had this dream about ten times (as far as I can remember). I'm not posting it because I had it again, just thought that if I should share it anywhere, this is the place...

An alien race comes down and in the process of trying to kill all of us, it releases a plague of diseases on us. This plague infects its victims by reducing the victim's brain capacity to it's bare necessities (food). It also pales the skin as a side effect (making UV rays harmful to the skin), thus making them nocturnal hunters. In a nutshell, zombies...
And that's where the dream comes in.. Only a few aren't infected, my family is one of which. We fortify our house, trying to keep them out, attempting to survive in a world like this. We catch wind of a cure being made by a scientist somewhere in town. skipping ahead... I found him at the top of a tower (strange because there isn't a building above four stories where I live). I think it was a clock tower, but I can't be sure. Looking down we see the zombies storming the building, we have no way out. With the vile holding the cure in my hand, I jump off and wake up.

Any thoughts?
