What is luffy's dream?

According to various characters who have overheard it, Luffy's dream is more ambitious than simply becoming the King of the Pirates. It's a dream so grand that it causes those who hear it to react with shock, disbelief, and laughter.

While the exact details remain a secret, it is heavily implied to be something childish and seemingly impossible, reminiscent of the kind of grand ambitions children often have. Both Gol D. Roger and Portgas D. Ace shared a similar dream, suggesting it is deeply connected to the concept of freedom and perhaps a world where everyone can be happy. It's a dream that only a select few, including Luffy's closest crewmates (the Straw Hats), Sabo, and Shanks, are aware of. Revealing the specifics is likely intended to be a significant moment in the series' climax.
