Oh man, ever since I've started rereading the books, I've had nothing but Animorphs related dreams.
The first one I had that I can remember, I was with the group, and all 7 of us morphed wolves, and there where these guys chasing us. I think they where controllers, but they had shotguns. For some reason, none of us could (or would), turn around and fight, so it ended up being one of those dreams where you just run and run super fast over terrain. We kept trying to find a place to hide, but they always found us. It ended with us all hiding in an empty water tower.
The second one I had that is notable was a few nights ago, I was a female andalite and I was prisoner of Visser Three on the Blade Ship, it was weird because I couldn't leave or fight back (seems to be a recurring theme), and I wasn't infested with a Yeerk. The Animorphs came to rescue me, but I kept telling them "no, you don't understand, I'm his sister!" over and over, but they wouldn't hear it and where mad at me for not trying to escape.
Another one I had, I was a controller, but the Yeerk didn't control me completely, we where friends and he told me I could do what ever I wanted as long as he had the ability to see... that's all he cared about. I went to a painting class in my dream (I go to art school irl) and he kept telling me how much he loved colors and how much he loved being in my head, I even let him take over so he could try painting. Later, I was in my mom's kitchen trying to explain to her that being a controller wasn't all that bad, and the Yeerk left my head so she could see it, and the dream ended with him in a Tupperware container full of water with me petting him and my mom freaking out.
The last one is the most disturbing. I was a Hork-Bajir in the barn, and all the Animorphs where standing around me, really pissed off, (especially Jake), and I kept telling them I was sorry, and Jake except saying "just give it up already, we need it to win this fight". What he wanted was some organ I had, and I sliced open my stomach and rooted around my insides until I found it. It was odd, because I knew it was an organ that only Hork-Bajir had, but I couldn't figure out why they needed it... and especially from me. I gave it to Jake and died right before the dream ended... really creepy.
