To Be or Not To Be a Zombie?

I think I'm a zombie but I have no strong desire to eat anybody's living flesh. So, maybe I'm not a zombie? My commander is leading our small group and we are barricaded inside a warehouse of sorts. I don't know what's going on really but I feel safe.

Metallica's Hero of the Day song was playing in my head when I woke up. Wonder where that came from?
