It was like watching a zombie movie, but in my head.
It starts in a theater, someone gets bit by an already infected zombie in the neck and the transformation is bother painful and instantaneous. He then goes on to attack other people. Thus, chaos in sues.
We join our main cast, a group of six young adults of different shapes, sizes and colors. Also in the theater, smart enough to run but one member doesn't make it.
The dream continues with the group running from what is now mass hysteria a mixture of zombies and desperate people. Eventually they, along with other survivors barricade themselves into a warehouse or garage of some sort. But of course one of the ones inside has been scratched and is infected and turns before they notice. This sort of thing continues on them running and trying to hide. The last location they hide in, in my dream, is a subway. whoo subway.

And I think they were all fucked in the end, but I woke up before it was finished.
I remember that if they Zombies bit you, scratched you, or bled into any orifice you would turn. So standard movie rules I guess. Also, they were fast zombies, but like the dawn of the dead(remake) jogging zombie, not like 28 weeks later. These were living dead.
