Do Elves need any sleep at all?

[Amanaduial the archer]

Dolphins sleep with only half their brain at once, while the other half stays awake if that is any help

hang on, very interestin, but relevant...how?neway, ]if we r into interesting yet fairly useless facts, killer whales sleep while swimming, in rows so they can support each other and bob up and down occasionally to get air....ahem....
however, has ne1 read Beyond The Deepwoods?it has a creature called a caterbird(this is relevant! or as relevant as the dolphins-no offence!)and they dont really properly sleep but they let their minds wander in between all the dreams every caterbird has ever dreamt,as well as dreaming some things into the future.this is why they r so wise.i think elvish sleep may be something like this.
lol
