Was That The Point? - Tumblr Posts
So ... what I'm hearing is he really needs someone to hold him while he sleeps.
Thinking about how Rimmer never looks particularly comfortable when lying in his bunk. He never looks like he relaxes all that much. I'm guessing that it's an issue formed from the terrible bullying he suffered from his brothers and at the boarding schools...
(also because Lister is a terrible snorer according to the books. In the novels, it is mentioned that Rimmer was beaten for little reason at school, including snoring.)
Anyway, it doesn't surprise me that Rimmer includes naps on his timetables...like yeah, between the anxiety and Lister's snoring, you're going to need to meet your sleep debt via naps.
Oh, that said I feel the possible sleep issues could also be due to his neurodiversity - whether it's the sensory issues or his mind not being able to quieten down.
