Zombie Attack

I was in a big one level shared housed where all of my colleagues and students were. I was in a auditorium like room and my students were creating projects with Freya's toys. My boss comes in and starts evaluating projects. I go into another room and put a dirty frying pan in huge sink that's almost like a fountain. There are a bunch of people in the kitchen doing various things, but the sink is full of murky water and dirty dishes and I can't find the pan I just put in there. The water is too gross to go searching for it. I decide to leave and try to get away with no one noticing, but the door knob breaks on my way out and I have to fix it. While I'm on the outside of the door fixing the nob a dog stares at me like a guard dog, but doesn't attack. I take my stuff and start running as soon as the knob is fixed. I run through a familiar neighborhood and make it to a random house. In the house there is an elevator (of course) and in the room with the elevator are a bunch of dead bodies. In my dream mind, I know they have been killed by someone. I ride the elevator to the top and I can't remember what happens on that top floor, but I know I hear an alarm and noises of distress below. I ride the elevator back down and the dead bodies start to rise. One of the dead gets up and demands we tell them who killed them. One of the people I'm with tells them something and they go off in search of their killer. I say "we have to get back to the library" which means the big house from the beginning of my dream. We leave the house we're in and run back across the familiar neighborhood that is now in chaos. Cars and vans crashed, people screaming, breaking windows, fires, etc. As I make it back to the house from the start of my dream a strange woman wearing almost no clothes tries to stop me by insulting my appearance. She grabs at me and I push her off multiple times and don't seem to shake her. At one point I have to throw her off of me. I wake up sore and tired from running.
