My gut tells me I have, but if so, I've forgotten them. Ugh, I want to remember one so bad. I feel left out. However, Pokemon have appeared in my dreams before. Here are a couple examples.
1st: A nightmare about thousands of snakes appearing out of nowhere. One or two were Ekans.
2nd: My first and only lucid dream, from a few years ago. Well, it was lucid for about two seconds. Basically, I was in my school library, and there were people walking around. Some were real people I knew, some were characters from Pokemon, some were from various other video games and anime. I saw two real people having a conversation about their moves, as if they were Pokemon. I dunno, but something triggered my sense of reality right then. Maybe the fact that NOBODY talks about Pokemon in my school, maybe the fact that they weren't Pokemon, something. I was like "Wow, this is a dream! Awesome!" and then I woke up. Dang.

Same here.i think I might've had one but I can't remember having one.

I know I had one, I just don't remember it.

I WANNA HAVE A REGIGIGAS!!!

I can't remember since it was a long time ago.

made up my own character and based it on the x and y episodes

Yes!!! I finally had one!! XD After I answered! I was a gym leader with Geodude, Onix and Milotic.

I had a dream that for some reason Jessie and James were around and so was my friend who literally lives in another state

I walked in and my friend is sitting on my couch next to Jessie who was in James' lap and they were being rly affectionate

and I started silently freaking out while my friend just stared knowingly at me

I'm such a Rocketshipper it haunts my dreams

I don't remember having a Pokemon dream. Munna probably came and ate them all.
