It was brought up in the thread about Dante, so I'm expanding on it.

Greybeard used to sleep head down, but now he sleeps just above horizontal or more upright. Maybe it's the influence of Chewbaca, who sleeps more upright, and for the last year has been sleeping on the perch beside him.

Could head down sleeping be a defense mechanism, where they could launch faster in case of a snake or other predator?
