I've had quite a few dreams involving Pokemon
most of the time I usually end up being a Pokemon been quite a few of them too
Been
Ninetales, Articuno, Yveltal, Dialga, Reshiram, Latias, Lycanroc, Rayquaza, Suicune, Umbreon, Braixen, Vulpix, Fennekin, Noivern, Zacian, Spectrier, Houndoom, Primarina, Lunala, Samurott, Lucario, Luxray, Raichu, Zebstrika, Dragonite, Raichu, Glaceon, Vaporeon and quite a few others.
Whenever I do have dreams of being a Pokemon not entirely sure what determines which Pokemon I end up as, so far at least it has been Pokemon I like.
I wouldn't want to be Moltres anyway.
Also had one kind of a mystery Dungeon type thing no mystery dungeons though, but had Espeon & Lucario as my partners and were on a team. Also had Kyurem trying to kill me a few times before Espeon & Lucario stopped him from doing so.
Another interesting thing is one I was Noivern in my eyesight changed and I was able to see soundwaves through dark caves and such was pretty interesting.
And this one is on a bit weirder side but had one with Moltres who threatened to kill Espeon in one of the ones I was Articuno in, and Moltres knew I wouldn't take a chance of that happening just so I did whatever he wanted, sometime later Moltres tried to synchronize every reality I've been in and planned on destroying them just to keep me in that one and he tried to destroy this reality as well and Moltres didn't seem to care what species I was either since he knew about this reality, and seemed to believe my original form is a dragon from another world since he planned on destroying that world as well.
Another one that involved this reality was one with Azelf one of which I was Dialga in Azelf tried creating time distortions using Celebi so I would become Primal Dialga take control over my mind then cross over into this reality from within my dreams to enslave the human race.
But Azelf didn't know I could turn into another Pokemon which I ended up turning to Articuno so Azelf's planned failed.
And some of the ones I was Yveltal in I did destroy a couple of planets, but they were beyond saving not sure if I should be concerned about being Yveltal or not.
But yeah have some that can get pretty crazy.
