You know, I look at your usertitle, and I look at your avi, and I think of your avi doing Can't Touch This, except it's "Do-the-Wess dance! *Mixed chord from Can't Touch This*" instead of "Can't Touch This! *Another mixed chord from Can't Touch This*".
Also, your profile picture gives a whole new outlook on Eusine X3
Well, if you're telling a short story based on the dream (or telling it like a story), then fics can fit, but if it's just 'I had a dream, and it was ___' and you want people to also post their dreams and have it as a discussion thread it'd be elsewhere. If you only want people to discuss dreams about Pokemon, Pokemon General would be best. Otherwise Other Trivia.
