Well, in fanfictions, Naruto might always be sleeping because it could be a plot device. For example, it could lead to him having prophetic dreams. Also, it could be a way to make other characters worry about him. His friends might think he's ill or something's wrong with his chakra. And perhaps the author just wants to show a different, more vulnerable side of Naruto that we don't often see in the original series.
One reason could be that he's overworked from all his ninja training and missions. In fanfictions, authors might use this to show the toll it takes on him. Another could be that he's having some sort of internal struggle, like nightmares related to his past traumas, and sleeping is his way of escaping or dealing with it. Maybe he's also been affected by some sort of jutsu that makes him sleepy all the time.
In some fanfictions, Naruto's constant sleeping could be due to a curse. This curse might be placed on him by an enemy he made during his travels. It's also possible that he's simply exhausted from constantly trying to improve himself and gain the respect of the village. The fanfiction author might use this as a way to explore how the other characters react to Naruto being in such a state. They could either take advantage of it or try to help him, which can lead to different story arcs.
One possible reason could be misunderstandings. Maybe Hinata says or does something that Naruto misinterprets in the fanfiction. For example, she might seem to reject his feelings in a really harsh way that breaks his heart.
One possible reason could be the weight of his past. Naruto grew up as an orphan, constantly shunned by the villagers. In the fanfiction, this feeling of isolation might be intensified, making him constantly depressed. Another reason could be the pressure of his goals. He aims to become Hokage but might face numerous setbacks that make him feel inadequate and depressed.
If Naruto is always sleeping in a fanfiction, it can completely change the power dynamics. His friends may have to step up and take on more responsibilities in his absence. This can lead to character development for them. Also, it might make Naruto a target for those who see his weakened state as an opportunity. All these elements can greatly shape the plot of the fanfiction.
One possible reason could be stress. For example, if you have a lot of work deadlines or personal issues to deal with, it can keep you awake at night. Another reason might be an irregular sleep schedule. If you often change your bedtime or wake - up time, it can disrupt your body's internal clock.
Another reason could be related to his relationships. Maybe in a fanfic, Naruto has a falling out with his friends like Sasuke or Sakura. This emotional hurt can be just as painful as physical harm. The author might use this to show how Naruto grows and overcomes such internal struggles.
One interesting 'Naruto Sleeping Beauty' fanfiction could be one where Naruto discovers a hidden village that has a curse similar to the Sleeping Beauty story. Maybe he has to break the curse using his unique ninja skills.
A great 'Naruto Sleeping Dogs' fanfiction could involve Naruto being mistaken for a local gangster in Sleeping Dogs' world. As he tries to clear his name, he discovers a conspiracy that links the ninja world he comes from and the seedy underbelly of Sleeping Dogs. He then has to use his wits, ninja training, and newfound allies in the Sleeping Dogs world to expose the truth.
It could be due to the failure of protecting his village or his loved ones. Naruto has always been about protecting those important to him. If he fails at that, his anger is understandable.
One reason could be to show a different side of Naruto. The original Naruto is very social and friendly, but in a fanfic, making him antisocial can create a contrast. Maybe the writer wants to explore how his friends would react if he suddenly changed.
She might be in pain. Maybe she has a headache, a stomachache or some other physical discomfort. Check if she needs medical attention.
