Normal Nightmares?

You know, to be honest, I'm not really sure what a normal nightmare is. It's rare that I even have them, honestly. I'm not great at it but, most of the time when a nightmare starts, I'm pretty good at pulling a little lucid dreaming and change things around. The other night, though, I had one that for some reason has been sticking with me. Of course, it's a dream, so I'm sure that it's been influenced by a hundred and one other things that have been going through my head.

It started with a mine digging deep into the earth. Digging a new shaft, the miners uncover a wall. Not just thick rock, but an actual constructed wall of dense stones, it's covered in odd complex patterns, but nothing that is close to being recognized as a language. The order is given by the owner of the mine to destroy the wall and any evidence of it, since it would cause the entire mine to be shut down while archeologist would try to figure out what it was.  When the wall is broken, a green mist escapes, enveloping the first of the miner's. From there, the mist spreads, and then dissipates quickly into the bodies of the terrified workers. Within minutes, the infected are attacking everyone in sight.

From there the dream becomes a "zombie apocalypse" kind of dream, with a group of survivors and "uninfected" holding out in a nearby school gym. I still remember the sounds of the "zombies" running across the roof, the weight of the makeshift maul being used as a weapon, waiting for the end.

The thing I found most interesting was that the zombies virus wasn't really a virus. It was actually a quickly replicating cluster of nanobots. The initial hive begins as an airborne swarm. Once it enters a suitable host, though, it becomes blood-born. It's passed via bite, the mouth of the zombie becoming akin to a komodo dragons, only filled with the nanobots instead of bacteria.

Once the nanobots enter a victims bloodstream, they quickly begin replicating and attacking/rewiring the neurosystem of the new host. In the end, the victim's neurological pathways, including the brain, are converted, killing the host, but allowing the body to continue to move, driving towards more victims. In time, the nanobots begin to adapt to their new bodies, the more nanobots in a body, the more cunning they become. Unfortunately, the body cannot maintain it's state for a prolonged amount of time, thus the process of decay begins in a host. Also, attempts to nourish the body compel the nanobots to attempt to feed the body in an attempt to maintain the body, but since the body is dead, all attempts to provide substance fail, in grisly fashion.

That's the idea I've had stuck in my head lately. Not sure what else I could say or do about it, but I think it's kind of interesting.
