The Time I Witnessed the End of the World because Congress Couldn't Agree on Anything

Last night I dreamt that I lived in the future and university was just a place where geniuses dressed in gray jumpsuits with white racing stripes sat in a circle and opened their minds so that blue and purple energy came out and flew around the room. I liked to joke that my mind was so open that soon it would be empty, but I wasn't completely joking. My professors said that mindpower was like love—the more you gave, the more you produced—but I wasn't sure they knew what they were talking about. One of my professors was a little more intelligent. He looked like the dad from Bonanza who I guess was on the old Battlestar Galactica because I saw like two minutes of it once when I was flipping through the channels. (So that's where him in space comes from. It would have been super freaky to see the dad from Bonanza in a space-traveling future if I hadn't seen him on an SF show!) Earth was very full of people and almost all city. I don't think we produced much of our own food anymore.
Anyway, suddenly this huge white alien ship that looked a lot like the International Space Station at a hundred scale docked in our upper atmosphere and started either sucking out or poisoning the air (or both). This alien race also cut off our food supply. Our world congress contacted this alien race, who were the Star Trek kind of alien in that they looked like gray people in fancy high-shouldered robes, and asked them to stop, pretty please.

The captain of the alien ship said his people had decided that our planet was overpopulated, corrupt, and a drain on galactic resources. However, as we watched this speech on TV, my smart professor told me that he had inside information that these aliens were really experimenting on us to see if their atmosphere-stealing equipment worked, how fast it worked, what the average planet's response to atmosphere-stealing would be, etc. They wanted to use the technology on their enemies, but they had to experiment like the US experimented with nuclear weapons in the Marshall Islands after WWII.

As we gradually ran out of food and air over the coming weeks, people started going nuts. People fought over the last candy bars from vending machines. Others committed suicide. My university held many extra mind-opening sessions, hoping our combined brainpower could blow the alien ship away. Congress couldn't decide on any course of action besides asking nicely. If we prepared weapons to attack the ship, some feared we would draw the wrath of the whole alien race. If we tried to sabotage their equipment, some feared we would fail.

At some point for some reason, my sister and I snuck on their ship and ended up eating crackers, grapes, and brie that the aliens had lying around. This was interesting because we both are allergic to penicillin and therefore have no business eating brie. We both knew that, but we were so hungry that we decided to risk anaphylaxis and swallowed it anyway. I skipped the crackers though because I'm gluten intolerant. An alarm went off when my sister and I took the food, so we went running off still chewing down the white metal grating walkway—so loud!—as the aliens chased us. They stopped chasing us once we hit the ground though because Earth is outside their jurisdiction.

Finally, as the planet's population came closer to total destruction, my smart professor and I flew out into space in his little silver spaceship and used our minds to put the alien ship in a time lock, so that this one pink-and-white shuttle kept detaching from the ship, flying a few yards, and snapping back to dock. It was only a temporary solution, and then I woke up.
