What does this dream mean?

Alright, well this dream was weird, and I didn't watch any scary movies or anything. So I dreamt that I saw this family and it was like an old family and the were in a wooden house, like the pilgrims, they were fighting. Then they made up and when they did there was an earthquake and the ground broke right in between them. One of the kids fell in and then the dad started teaching the kids what to do. He was teaching them to act like zombies. after that everything for me was in this girls point of view. She faked it well, and then the man took her all the children zombies were walking and all of them were pretending, then, I realized I was myself and not the girl anymore. We saw this girl, who was a real zombie, oh and the zombies looked like people they just wouldn't act like it. And and she was the best real zombie, she went jumped And caught a pigeon and killed it. By the way right when I was myself I was in my neighborhood. Then, another pigeon flew by and when it was close enough I grabbed it and twisted it then dropped it on the ground, so that way I could ensure everyone that I was a zombie. When I twisted the pigeon, the mom of the family before died, and the little boy from the family said how could you, so even though I looked like me I was still her. We continued to walk however and we saw the boy he tried to act like a zombie but failed, and the chopped his head off as we were walking, there were these purses, but not real one s they looked like they were made from the stuff the make those sweetheart Valentina candies from. Anyway, we all had to take huge bites of them since that's what zombies do. I bit the yellow one and I tasted like cardboard, after that this girl came up to me and said, I know you're cutting and I said no I'm not. I guess she meant cheating on acting like a zombie, so by this time we were by the park in my neighborhood and there was talk that we were going to move on to the next level. I guess they meant another planet, but I couldn't do it anymore so I randomly knew it was a dream and I woke up.
