Although it's quite the undertaking, you understand that you have to start small to make big changes. Unfortunately, even the most exciting politics are boring and slow, full of bereaucracy and bullshit. Fortunately, Morpheus has the power to spare you all of that. You start by running in the city council, working on a law degree while you do it. Eventually you move up to being the mayor of your locality. You steadily progress through offices, from governer to senator to dungeon master and finally to president or, if you're into monarchies, maybe you get elected to be Queen.
You change the world, everybody is happy, there are documentaries made about your life, and...well, that's about it. Although you want to be fulfilled by your accomplishments, the process does seem a little rushed, maybe even inauthentic. Maybe it's because it was all just a few minutes spent dreaming? When you wake up, will the world still be different?
