I had this dream when I was about 7 but remember it absurdly vividly and with abnormal amounts of detail.
I was on a foreign planet that would occasionally get little tornado looking black holes. If you got caught by the black hole you ceased to exist. I teamed up with some kids I didn’t recognize and Sonic the Hedgehog to fight them, but quickly realized you can’t fight something you can’t touch. So we said screw it and continued on with our lives. That is until sirens started going off warning us that the world was ending and that a black hole tornado was going to destroy the entire universe. The only way to survive was to get into the safe house. Thousands of children flooded into this weird bunker thing. When I looked in, though, I saw it looked like my elementary school. I spent a good minute debating on if I wanted to be in school for the rest of my life. When I decided that I didn’t, I turned to go back to the surface. Sonic asked me what I was doing, and in the most badass apocalyptic hero voice I told him I was going to save the universe so I wouldn’t have to go to school. Then I woke up.
