Does anyone know what Zombie Dreams mean?

Warning: Weird Dream (btw I'm not faking or weird this dream is 100% true)
So I recently had a dream about the zombie apocalypse but it was weird. It took place at school with my best friends, and we were trying to escape the chorus room. Somehow we ended up in the bathroom, and had to escape cuz we were being chased by zombies. We ended up in the chorus room again, where there were two zombies. One was trying to eat us, the other was questioning us, but it let us go because we "passed the test". I know it's weird. Btw the Zombies looked like cartoon bobbleheads with perms. So then somehow I ended up at some house without my friends, and with a random family I'd never seen in my entire life. There was a little boy and a little girl, a dad, and a mom, who turned out to be my family in the dream. And then the zombies ended up disappearing to some random place, and none were at the house so we went to petsmart to buy food which made absolutely no sense, because both of my pets died in the dream. :,( Then we came back to the house, where there were tons of zombies so we walked upstairs to a random bridge which led to a treehouse that appeared out of nowhere. Then I woke up. What the heck does this dream mean?!?! Please don't call me weird or a freak or anything. It's not my fault I have weird dreams.
