This one's a bit of a doozy.

I remember going to a sort of "pub"/gift shop thing with a REALLY awkwardly designed bathroom (with actual bathtubs) and p!ssing on a text-to-speech voiced Rouge the Bat, finding a VHS of episodes of the DIC Mario cartoon where there was this weird alien that goes "I'm angry, I'm REALLY ANGRY" and transforms similarly to The Hulk, and finding a weird fake Gatomon MUGEN character that was a spriteswap of a spriteswap of a nonexistent "Killer Zoroark" character which i actually played as at one point. It had a really long, flashy super about "consuming the meat" or something, where creepy Zoroark art would flash on the screen breifly, portraits of other characters would show up and be crossed out with gory sound effects until it's actual portrait would be all that was left.

Like a lot of the dreams i have, this is ONLY the highlights. Honestly the Mario and Sonic stuff was kind of unexpected for me to dream about.
