Animal crossing theories:

In animal crossing new leaf, Gulliver mentions different places in the world he talks to you, so your town must be somewhere in the world, there are OTHER humans you can visit. But when my friend and I where on Kapp'n's boat, he mentioned that he looked like me at a younger point of his life. So, he looked like a human when he was younger... interesting. After not playing for a while your character will come out of there house and yawn. My friend hasn't played in months! No one can last that long asleep without food or water. The only question, how do you stay alive while in the deep slumber. Well, what if your town is a dream. When you go to sleep at night that would be your town. How else could you explain the idea of the fact that you can hear animals and you're the mayor of a random town in the middle no were.

Your parents were very rich people who couldn't handle it when you were put into a coma. You were always very alone as a child, and had no friends besides the hospital staff and a few stuffed animals.A few weeks after you fall into a coma, a new company releases revolutionary technology. It allows scientists to reach into the minds of comatose patients and try to wake them up. Every patient has a trigger, something that will wake them up from their coma.Your parents hire a team of scientists to help you wake up. They appear as the Villager NPCs. Every person's 'dream world' is different, hence the different maps/villagers.

In this world, people also interact with humanoid like Animals. The two groups co-exist and live together without much bickering, since the humans help the animals and vice versa.You are a young teenager who wishes to leave their home behind and start your own, new life. One day you leave your home behind and go on a train, bringing with you absolutely nothing. All you know on the train is where you're going. You fall asleep on the train and when you finally wake up, annoying stupid Rover wants to make small talk.Being alone in this new, scary world you happily comply. Rover eases your nerves and once you enter your destination, you aren't so nervous.Mom checks up on you most of the time, since Dad has a busy job. But in your town, you've made new friends and are living a great new life.Maybe all towns are connected by one train line, and each town is like a "county" with it's own unique land and villagers.

we are all gyroids, which would explain why we can't actually speak, and only make a few little noises when expressing ourselves, much like a gyroid does through singing. The skin of other humans gets layered over our faces, but if we haven't been outside for a long while, it begins to rot, and our real faces are revealed. But, they must've done a better job of keeping the skin stuck to our faces in the most recent instalments.
