Quantum Blue, Neo wake up, it's already the 20th alpha! Adamantium zombies? What's next, maybe a zombie piloting a shuttle or a zombie mage and a summoner? Freedom of thought and flight of fancy - this is chained to the existing realities and known physical laws, everything else is damn Narnia with Harry Potter!
And by the way, you are very good at rewriting history, remakes and substituting concepts, you succeeded in this (generalization) in the real world with your flight of fancy and freedom of thought. In fact, this is called a fat frenzy, when always full looking for new tastes and new foods to become full. Try not to eat for two days and oatmeal will seem extremely tasty to you. The world is already on the verge of starvation and resource shortage, so already now you should not count on a daily lobster with a cigarette of marijuana.
