Some people say that a person dreams what they think of as so proven by Ji Yao who dreamt about the most clingy Nocru on earth. In just a space of a few hours, Rui Fei had influenced him so much that he left an impression so deep to the point of appearing in his dreams.
This is why he woke up with a start calling out Rui Fei's name which in turn woke up the boy cosied up on the chaise. Thus the conversation mentioned earlier about who kicked who off the bed and that the other was lucky he didn't get kicked out of the cabin.
Ji Yao lay back down and tried to go back to sleep again but it seemed the bogeyman a.k.a. nightmare king wouldn't let him off. After dreaming about Rui Fei for the nth time, Ji Yao finally gave up on sleeping altogether. He sat up straight in the dark cabin with the only source of light coming from the moonlight outside the window.
