Dreaming about Zombies

I had a dream I was in The Walking Dead.  Well, more so I was just in a zombie apocalypse and Glenn was also there.  A group of us had been on the road for awhile when we came across a place that had basically been untouched, like Alexandria. People there weren't worried about anything.  They were still using their phones as cameras, taking selfies with the walkers in the background.  Staying there made us soft.  Glenn and I went for a run and we were talking to my fiancé on walkie talkies and we were looking for a gun store and I was like, can you tell me the address I'll put it in my GPS? Then I realized, my phone's GPS doesn't work...duh. Then I started freaking out, thinking how will I ever know where anything is without Google and without a GPS?  I used to think I'd rock a zombie apocalypse..but now? I'm not so sure.
