I felt like Lee's dream was a homage to Naruto SD :|Lol no one puts Lee through shit when he saw Sakura in his dreams.
The thing with comedic IT dreams was this: they go in a perfect world. People have perfect dreams and perfect little problems. Ino does not see her father coming back because in a perfect world he is not gone. Hinata, Lee, Tenten do not see Neji coming back to life because in a perfect world that is not needed, he is granted as an usual teammate, sibling or rival figure. Mei does not see the better village after bloody mist, it already exist. Her perfect little problem is marrige.
That's what happened with most characters. They saw comedic things because the things which pained them never happened.
Only exceptions are Tsunade and Gaara who did not even experience those garnted things to a normal human.
I don't see much sexism about that. Kishi is not good when it comes to females, but this chap did not make anything any worse.
It's still a problem though. Can't the girls have non-male related dreams, big or small, like non-female-related dreams of Shino or Kiba? And notice how Tsunade isn't even Hokage in hers. In her perfect world she leaves the leading role to the man. I swear if it was my dream world I'd be the most powerful being in a universe - not because I hate men but rather just because.
