I had one, maybe a week ago. I mention it in another post, but I didn't really go into detail.
It starts with me waking up (in-dream) to the sound of someone banging on the closet door, like they're trapped. I get up, and walk through the room to see what's going on (it wasn't my actual room, or house, but I didn't notice at the time.) I open the door to find a Zelda: Ocarina of Time-esque fairy, who informs me that I am to become an apprentice of the god Okami (whose game I've barely even played yet).
There's another scene, which involves me and my brothers travelling through the night, and it had something to do with Pokemon, but I don't remember it well, so skipping ahead of that, next thing I know I'm walking down the stairs of my actual house, like I'm just getting up in the morning.
I walk into the kitchen and see a giant pile of purple sludge. At first, I think it it's a Muk, but I pull out my handy-dandy Pokedex, and it tells me that it's actually Muk's nameless evolution. It is slightly smaller than its pre-evo, and shaped like there might be some kind of headless mammal underneath its slime. It has a really creepy, slightly Digimon-ish face, that has evil-looking eyes, and a mouth that appears to be in a giant cat smile, though it isn't actually smiling. The Pokedex informs me that it actually is outright evil, and that it hated everything.
Geez, how did that thing get in here? I think, as I skirt around it to get to the back door. I figure someone would come over and move it out eventually. (Apparently, my dream world is a place where a giant, villainous pile of ooze is no more threatening than a large spider. To be fair, it moves really slowly, and it's much easier to keep track of than one.) Once outside, I go over to the large trampoline where my friends and brother are bouncing, and join them.
After jumping around for a little while, I look towards the back door, and out comes some kind of Pokemon trainer, who has green hair, and he actually looks like an anime character, as if a piece of gen 1 or 2 artwork had just peeled itself off the page and started walking around. I'm kind of scared for a moment, because I think he's supposed to be a villain, but then I realized he's actually an Elite Four champion. He climbs aboard the trampoline, and is followed by his apprentice (who was a little girl that looked too young to even be a trainer). They challenge me and my friends to a team battle.
I'm pretty scared of this, since I only have a level 4 Marril, but for some crazy reason I accept anyway. I send out my Pokemon expecting the worst, and I figure my friends feel the same way with their Pokemon. But the Champion and Apprentice just send out low-level Pokemon as well, and it turns out, their attacks aren't strong enough to do any major damage to our Pokemon. Though, ours weren't very powerful, either. basically, it was the lamest champion battle of all time. At some point, the battle was interupted when I noticed the Muk evo slithering past the trampoline, and Professor Oak coming outside to tell us something along the lines of "Breakfast is ready!"
Sad thing is, that isn't even close to the weird dream I've ever had.
