I've had several crazy dreams in the past, so I'll go pick out the weirdest one I've gotten yet. Copy-pasted and edited from a text file on my computer, here it is:
The dream started off with me watching
the "maximum coins" TAS of Super Mario Bros. one night. I was just watching it entirely out of boredom, and nothing was wrong; it's just about what you'd expect from three dudes that are way too freakin' good at TASing Super Mario Bros.
Nothing was wrong with the movie during the first half, but the TAS froze the game for a brief moment sometime around the beginning of the second half. It then continued on like nothing had happened, but then I started to see what looked like someone had corrupted part of the ROM. The levels and their associated graphics got jumbled up beyond recognition, yet the TAS went through them like they were perfectly normal. Even Mario looked normal, but I guess it was just a testament to the insanity that was going on.
By the time the TAS got to World 6, things got even weirder. The graphics were back to normal, and the levels were normal as well, but almost all of the palettes were being turned into strange varieties of ugly colors. Around the time the TAS got to World 6-2, I started seeing enemies and bosses from all of the later Mario games that were released on the NES and SNES, Mouser (from SMB2) being amongst them. The TAS still continued normally, and yet I never knew what the Hell was going on. Did it somehow manage to execute arbitrary code? If it did, then HOW did it manage to do such a thing? Who knows?
I don't remember a lot more of it, but I think I watched it to the end just to see what other cameos would surprise me. Maybe Wart got involved at one point? Again, I don't remember.
