I never said they didnt have dreams, I meant that the character does need to literally say "My dream is ..." for you to know their dream, its very much inferred through their dialogue and characterization, Brook wanting to fulfill his promise is his dream, Jinbe wanting to change the world for the better for the sake of the fishmen is his dream, and Yamato wanting to be free is her dream, they dont need to scream it like they were Luffy
