Note: I ran out of ideas and the sequels to existing works need more time, so I'm trying writing from prompts.
Sleep
Prompt: "I was sure that rotten boy was sleeping all night."
Mikkel claimed Reynir had always had trouble sleeping during the night and, what had happened had probably made the phenomenon worse, hence explaining his irritability as of late. There was one problem in that explanation: if Reynir really had trouble sleeping, Emil should have, by all means, witnessed it by now. Each and every time he woke up from his own nightmares, it was to Reynir breathing the way soundly sleeping people usually did. As far as he was concerned, Reynir was sleeping through the night, while he wasn't. The only thing that kept him from complaining too much about it was that Reynir's breathing contributed to the soothing ambient noise that helped him go back to sleep if he focused on it long enough.
How did he always manage to bump his head on Emil's bunk when he woke up after dream walking? Reynir always half-expected to hear Emil's sleeping voice complain each time this happened, but he fortunately seemed to be a sound enough sleeper to never be bothered, no matter how many times it happened. It was probably for the best. After he had made sure via Tuuri that Emil knew he hadn't minded the manhandling from that first day, they really hadn't had anything to say to each other. However, Emil was friends with Lalli, and the latter's relationship with Reynir was quite complicated. Lalli didn't like him as person, but follow-ups on what they had planned in the dreamscape the few times they had been asleep at the same time frequently happened in the physical world. A lot of it was communicating about things only they could see using drawings and gestures, resulting in a strange cycle of understanding each other in spite of the language barrier and one of them getting frustrated with the other's lack of understanding. Emil was a regular silent, but very visibly and understandably baffled, witness of these moments. After Tuuri's troll bite, the yelling had become more frequent than the understanding. Now, Emil probably viewed him as the guy who kept yelling at his friend. Last thing Reynir needed was to become the guy waking him up at night in addition to that.
