I think I know where I got this dream, though I don't remember if I saw my brother watching it Saturday or Friday, whichever of the two days.
Well, it first started with my brothers and I attempting to “escape” our backyard to go to the school that was somehow across the street. They got away first, and I hesitantly jumped down and nearly avoided traffic running onto the grounds. As it turns out, due to the schedule I had in my hand, I had missed the first two days of school, and I was going to be late for seminary on my second period. (Keep in mind that this is supposed to be a high school, and I've graduated two years ago.) So I ran over to the church building, again nearly missing getting hit by school buses.
When I went inside, it turned out to look more like my grandparents' house than a church building, though it had some add-ons to it. I noticed there was a small aquarium with beta fish, but because they were all different “species”, they left each other alone. I then noticed some instruments lying around (it looked more like Rock Band equipment), and I picked up the bass for a moment and messed around with it. Then I went to class.
Nothing much happened, except that we were doing a crossword, and I could see the faint red answers on the projector, despite nothing being written on it, yet. I noticed there were about six names, including mine in the puzzle. I recognized one (Stephen), and I turned to the guy behind me, and went, “Dude, Stephen, right? Your name's on the puzzle.”
He almost didn't believe me until he gave the answer on the puzzle, and it faded in black. The two of us freak out, and we end up running outside to go look into the room. As it turned out, he had picked up one of the instruments himself, and he developed some powers of technology, and he could transform into Tech E. Coyote. Meanwhile, I had developed come form of psychic powers or something similar, and I was Lexi Bunny. After going around the building for a bit, we found another boy who was Ace Bunny because he picked up the guitar, and we spent time looking for the other team members.
I found someone I knew was going to become Slam Tasmanian, but he hadn't touched the drums yet, and he was confused at how I was persistent in being careful. We hadn't found the other two yet (though I thought I saw Rev Runner, and we forgot about Danger Duck until someone pointed it out), but we discovered that a girl had become a villain in the form of Petunia Pig. She had crashed through a window to the school grounds below, and some other kid accused us of wrong-doing, so we jumped down to the grounds ourselves, and we began having a brawl with the Petunia Pig girl, though I don't remember her powers.
There's more to the dream, but I can't remember it, except that I KNOW there were mentions of Marvin the Martian involved somewhere. So... yeah. It was as strange as you think it is, but I think it's a better dream than the ones I tend to get. (And I'm pretty sure I got Lexi Bunny's powers wrong.)
