I've never had AN related nightmares before until now. :'D One was that it was already a week before AN and all the things my boyfriend and I ordered (wigs, worbla, etc.) never came in and we couldn't do anything. :c
Second was that we forgot when AN was and all our friends came to our house in cosplay waiting to leave for the con while we had nothing finished/packed and went to the con without anything and we're really disappointed.
Anime North '13:
Hilda/Touko - Pokemon: Black & White
Monkey D. Luffy - One Piece [Impel Down]
Yamuraiha - Magi: The Labyrinth of Magic
Maybe? Aoi Asahina - Dangan Ronpa
