Lately the thing about Luffy actually having another dream (WSS, All Blue etc.) has taken more of a center stage. I don't know what the timeline is when Luffy first declared each of his dreams. But I think that there is a distinct possibility that one of these dreams is actually due to the Nika Nika DF. Piracy has been shown as a means to freedom/being free. Earlier it was to surpass Shanks and his crew. But reaching Laugh Tale and becoming PK seems to have come later on. But then so many other pirates also have the same goal of becoming PK by finding OP. Willingly or unwillingly they have all inherited the will or rather the purpose of Roger. So the PK dream is probably a natural evolution of desire for freedom.
But what about the other dream, the one the readers are yet to learn? We know Zoans have a will, so can they also have dreams?
