A number of them, not always memorable. The first one I had involved meeting Jessie and James in a church and helping them out (because this Jessie and James, for whatever reason, weren't trying to be villains).
I've also had a number of cracked-out ones, including:
1. Seeing Zapdos at the end of the world. As in, seriously, the sky was on fire.
2. A party in a boathouse where a spirit of death was wreaking havoc and randomly stealing souls. So, Ash (who was accompanied by Brock, May, and Max, none of whom really interacted with the spirit) and Bill attempt to lure said spirit out into sunlight, therefore destroying it. There was apparently something special about one of their souls, which would have led into another "episode" that took place the next day if I hadn't woken up just as it started. I think Bill was going to end up being a death spirit as a result of this stroke of utter genius on the parts of both of them.
Oh, and the way they try to lure the spirit out? By dragging him out. By the arms.
Genius, I tell you.
3. Michael, May, Brock, Wes, and a cross between Misty and Rui traveling through the Orre region to destroy mystical stones that mutated wild Pokemon into becoming shadow Pokemon. Half the gang ended up staying/working on a ranch run by a hippie couple because they had to pay for the stew they keep eating, while Michael ran off because Wes pissed him off. Wes was about to shrug it off (because he was seriously a jerk in this dream), but Misty/Rui scared him into going. As in, anime stereotype, big head and dwarf victim. In any case, Wes went off on his hoverbike with the excuse that the stones needed to be destroyed by both snaggers, but when he tried to catch up, Michael outsped him in his scooter. This, of course, ticked Wes off (because he's on a blinking hoverbike), so when he went to apologize, he screwed up again, resulting in Michael running off again. Eventually, Wes finally caught up to Michael, just as a shadow Pokemon was emerging for the two of them to fight.
Naturally, my dreams end at the best parts.
