Zombie Attack

Date: 6/25/2016

In my dream I was at my regular old house except for one thing, zombies. In my dream every night zombies would go into everyone's yard including mine. My siblings would stay out to the very last moment. I would have to beg them to go inside. This felt similar to a previous dream because I knew it was a dream. When we were inside I would see other people trapped outside. I saw blood splash on my windows and saw a little girl die. One night there were different looking zombies. They looked stronger and less zombie like but still noticeably different. We still locked our doors and the windows. One zombie simply slid our door open and a few others poured in. They then tried to attack. My mom, dad, and I locked the others into the basement. We grabbed knives, hammers, and other tools and killed them off and locked the door. Then I woke up to my mom yelling at my sister for spilling olive oil all over the carpet. I was so relieved. Can anyone tell me what this means? I have recently had violent dreams and they have gotten worse.
