Idk how whoever he's talking about interpreted it, but to me, the chapter showed that Hinata's dream of being with Naruto is pretty much as possible everyone else's dreams (like Gaara's of having his family together, Ino of Sasuke and Sai fighting over her, etc.); i.e., impossible.
Though they won't. All of them were impossible, a huge lie like Naruto said.
Dan is Hokage/with Tsunade and Nawaki alive, Sai & Sasuke fighting over Ino, Kiba becoming Hokage, Shino finding a rare mega-bug species, Lee and Gai acting calm and cool, Shikamaru not being married because it's troublesome (Temari agreed hehe), Choji finding a woman who loves men who eat so much, Naruto and Hinata together, Mizukage getting married, Gaara having a good childhood/parents alive... it's all never going to happen. Harsh but true. It's gonna be a little heartbreaking when they wake up an realize it was all fake.
Yeah, this is pretty much what I said when the chapter came out. All of the dreams are probably impossible, but some of them are for sure.
Some of the dreams included people who are dead, or circumstances that cannot happen, or both. Tsunade's and Gaara's dreams are great examples.
Hinata's dream falls into the same category. Even if it was technically possible by assuming that Naruto's feelings could change and he would no longer love Sakura, Kishimoto made a point of including Neji in the panel -- signifying that the content of the dream was impossible. If Neji had been left out, there might have been more hope for NH.
And yeah, poor Shikamaru, lol. Looks like he's going to get married anyway, despite how troublesome it might be. $20 says Temari had a similar dream....
