i think there was a question like this sometime ago that said something like "when fia doesn't get finished off properly during sex she has wet dreams" which is definitely related; fia might not be a very articulate sleep talker but whenever she wakes lemmos up on nights like those with her wiggling and moaning and hard, lem and mos each jokingly insist that fia is dreaming about her and not the other. this is the case for fia, and i think its funniest if she had those dreams most often bc she'd be so embarrassed and squishy about it, but i do also think mos, who feels like the type to sleep talk, would make it funny if she did bc if fia woke up to mos moaning her name in her sleep she'd die
