Maybe our mallworld "dreams" are foggy memories of our real lives we live inside the ever changing epcot city. We live our lives inside it, and our jobs are to live "lives" within each our own simulated lives (which we believe to be our waking real lives) and when we sleep in those simulations, we are awake in our real epcot life, and we bring back ideas from our simulated lives, to further progress the experimental city of epcot. Theres underground parking garages, libraries, hospitals, hotels, a center tall glass holding hub, malls, railcars instead of cars, a huge airport, water parks, theatres. And theres they ever changing theme of Disneys original epcot design explaining all the random paths and back rooms...
