I get nightmares pretty often. Bad ones, in general, because I'm dead afraid of being alone and they're usually about that. And Sora and Tazuki probably have some, too. Especially Tazuki, because of the "dragon accident".
And what if, at some point, I woke up in the middle of the night absolutely terrified, and hesitates quite a bit before starting a call in our chat. I struggle to explain my nightmares, and just dreams in general because my universe is pretty complex, but as soon as I'm able to word it out, we just... Talk about it. They assure me that they won't leave, that they'll be there. And I promise back, of course.
As the night advances, we talk about our respective nightmares and fears. Tazuki probably listens more than he talks. Sora's a bit reluctant at first, but as time goes by, he opens up more.
We know that we're going through this together.
And then what if, like that, we fell asleep while on call. Together. Soft snores and *Mii-kun and Conny noises* are the only thing we can hear, but if anyone wakes up again for any reason, he knows that he isn't alone.
Someone told me once that "if we go to sleep together, we'll protect each other from nightmares" and, as silly as it may sounds, maybe it's not false after all.
