In some fanfictions, Naruto's sleep anxiety might be shown through his constant tossing and turning at night. He could be having nightmares related to his past traumas, like the loneliness he felt as a child or the fear of losing his friends. This sleep anxiety might also lead to him being tired during the day and affecting his ninja training and missions.
One possible reason could be the stress of his ninja duties. He has so many missions and responsibilities that his mind is constantly racing, making it hard to relax and fall asleep.
Yes, in some Naruto fanfictions, the author may explore Naruto's inner turmoil during sleep. It could be related to his past traumas, like the loneliness he felt as a child or the pressure of being the Jinchuriki. These elements add depth to his character and make the story more engaging.
One example could be a fanfiction where Naruto has nightmares about the Nine - Tails rampaging again and him being unable to control it. Another might be him dreaming about the deaths of his friends like Sasuke or Kakashi during his sleep, which causes him great distress.
It could be a genjutsu cast by an unknown enemy. This enemy might be targeting Naruto specifically to make him vulnerable. They could be using sleep paralysis as a way to weaken his mental state before a bigger attack.
One possible plot could be that Naruto wakes up in the middle of the night, unable to move due to sleep paralysis. He might see strange shadows or figures in his room that seem menacing. Maybe he tries to use his chakra but finds he can't in this state. As he lies there, he could start to recall past traumas or fears, and the experience could make him question his own strength and courage.
Maybe in the fanfiction, baby Naruto has a nightmare. Kushina then holds him close, reassuring him that he's safe. She could tell him stories about his father, Minato, and how they both love him very much. This would comfort Naruto and he'd soon fall back asleep in her warm embrace.
Yes, there are likely fanfictions out there with the concept of 'Naruto has a Kakuja'. The Naruto fandom is vast and creative, and fans often come up with unique crossovers and concepts. Some fanfic writers might be inspired to combine Naruto's world with the idea of a Kakuja from other series or create their own unique take on it within the Naruto universe.
Yes, there is. The world of fanfiction often combines different popular franchises. Naruto and Pokemon are both highly popular, so it's not uncommon for fans to create stories where the two universes intersect. These fanfictions can range from simple crossovers where Naruto characters encounter Pokemon, to more complex stories that blend the elements of both worlds like ninja using Pokemon in battle or having Pokemon in the Hidden Leaf Village.
Kushina would take care of baby Naruto very tenderly. She would make sure he is well - fed before sleep, perhaps by breastfeeding him or giving him a warm bottle. She'd also check his diaper and change it if needed.
