Missing time

This dream, my gosh this dream was a weird one. Back in September last year, I visited my friend in Atlanta which, if you did not know, is where they shoot The Walking Dead. His house is huge, four stories and full of so much stuff. I think The Walking Dead thing played into this dream a little bit. There were about 8 people in his house, a few people I knew, and a couple of people I did not know. It was not shown or explained explicitly, but we all knew that we were in some kind of reality show, where people would watch us being pit against zombies with indefinite waves. Essentially, they would send out the first wave of zombies, and they would be slow moving, and almost impossible to be caught by. Once we fought that wave and it was completely gone, the next wave would come. The next wave would be just a bit bigger as well as faster and stronger... so on, so on. It was very similar to the Call of Duty zombies if anyone has happened to play that. I actually mentioned this and we came up with the ingenious plan of not killing the last one, and just keeping our eyes on it so that we had a lot more time and we had a moment to breathe. At this point, time seemed to skip quite a bit to where there were just a couple of us left. I ended up getting split off and cornered, and I feared for my life as I was hiding in a room. I remember being so absolutely petrified of the pain that I would have to endure as I went down. I actually contemplated killing myself for a little while. I heard an announcement that the other two people had died, and I was the last one, and it was as that point that I decided I was going to keep going. I fought the few that were left, again leaving one. The very last thing I remember of the dream was sitting down in a room hiding behind a chair as I heard one of them come closer and into the room. I felt like I was a little bit exposed and as it left the room, I shifted the chair which accidentally made a noise. It came running at me and barreled over the chair, and I could so vividly hear the sound of it right by my ear. I then immediately woke up.
