Dreamworlds:

It happened in an instant. You, a young man about 6 foot-two-inches in height and who is about 23 years of age, had fallen asleep after playing video games and doing coursework on a Tuesday night. You were studying for the chapter finals of a course covering theories and concepts on the existence of multiple universes. And you thought you were ready, when you awoke the next morning not to the familiar sights of your room, but to a confusing sight of dunes and endless sands. Your first question which pops into mind then, being what of course, is this place? By what had you arrived here? And was it by any means, even real? Or had you been studying for the test too long, and now you simply had alternate worlds on the brain? Because if so, then you thought your imagination certainly could've come up with a nicer one.
You shake your head and sigh.
It seems in any case you have two options. Would you one, try to wake yourself up, maybe escape this dream. Or would you two, try to make the best of it. You look about and see what looks like smoke rising in the distance. Smoke usually means people. Maybe if this isn't a dream, you can go toward their camp, and ask if they know anything about what's going on.
