Does a post-zombie-apocalyse dream count?
Just the other night...too long to recount here. Never saw any zombies, just figuring out the new cultural structure. It was a full length narrative, many of my dreams are, and persistant enough that I can wake up, go back to sleep, and the dream picks up after it left off. One of the most interesting aspects of the new laws was a severe penalty for breaking glass window panes, as they were needed to build greenhouses.
It wasn't a nightmare, more like a documentary.
