You find something that doesn't belong

Despite the foreign surroundings, you are enthralled by the cosmic beauty of it all. On such miniscule distances, there's barely even enough light to be able to see. Everything is so... wait a minute, what the fuck is that over there?

You spot an irregularity. It looks like an object of some sort, stuck in the electron cloud of a silicone atom. You shrink down even further and wade through the murky, tingly electron cloud to reach the object. It's so dim that you can barely make out its features.

Sophie: "Is that... a planet?"

It is. It looks much like Earth, with ample bodies of water, greenery, ice caps, deserts and clouds. You take the marble-sized ball into your hands, above which it floats mysteriously.

Sophie: "This is spooky. How did this get in here?"

You decide to shrink down even further to better inspect the planet. Now you can clearly see mountains, river deltas and islands. The topography is completely different from Earth - this must be an entirely different planet. You also see something even more exciting - signs of development! On the far side of the planet you can see the city lights, and as you shrink down even further, road networks.

Eventually, the gravity of the planet begins to pull you in, and you begin to fall towards it. In order to avoid causing widespread destruction, you shrink more the closer you are propelled towards the planet's surface. Eventually you hit water, thankfully close to the shore, and by a fortunate chance also close to a city.

You re-grow yourself enough so that you can comfortably walk in the dozen-meter deep water and come onshore. The architecture here isn't spectacularly different from Earth, but some small details and odd features tattle about the foreign culture that must inhabit this world. You consider shrinking yourself to normal proportions before entering the city, but remember that your alien appearance would likely arouse just as much concern.
