Sure. There are likely fanfics out there that deal with the relationship between Sebastian and Ciel in a more chaste way. In a half - asleep scenario, it could be about the trust between them. Maybe Ciel is half - asleep and Sebastian is watching over him, and the story could explore the unspoken bond between them without any sexual undertones.
There are fanfic communities that encourage non - sexual interpretations of characters' relationships. For Sebastian and Ciel in a half - asleep situation, it could be a story about how their personalities interact in a sleepy state. For instance, Ciel's vulnerability when half - asleep and Sebastian's loyalty could be the focus, rather than any sexual content.
Yes, there could be. Many fanfic writers focus on creating innocent and platonic scenarios. They might write about a half - asleep moment between Sebastian and Ciel where it's more about a tender, non - sexual connection. For example, it could be a moment of Sebastian protecting Ciel while he's half - asleep, or Ciel having a dream and Sebastian being there in a non - sexual, comforting way.
