I think it's such a fundamental tissue of Gloranthan experience that it's rarely talked about.
IMG the theistic societies generally distinguish between "dreams" -- which are confusing, personal and derive from obscure sources -- and "visions," the interactions of the gods with your drowsing soul.
You want to have visions. Idle dreams are an invitation to trouble.
Smart people can interpret a dream and figure out what it means, where it comes from. They can also exorcise dreams that get in the way of clarity.
The visions are probably one of the clearest manifestations of the Truth rune we have. Dreams that stay dreams might as well take Illusion. The line between them is often mysterious.
People who pay a lot of attention to their dreams tend to operate in contexts we would call "mystical" -- the East, the Lunar Empire, EWF. What dragons and dragonewts do is called "dreaming."
Nysalor built a tower of dreams.
Siglat dreamed an impossible dream.
The line between dreaming and experimental heroquesting is razor thin.
> ( a idea for a orlanthi god or goddess of dreams?
Sorrowful Rausa is a mysterious figure and a good place to start. She's not exactly an Orlanthi goddess. An encounter with anybody's foreign god is a pernicious generator of imagery that your local ritual specialists can't interpret. Any night visions your local ritual specialists can't interpret is an encounter with an unknown god.
This can create poets or madmen. It's their initiation.
The Donandar probably keep their dreams on a relatively loose leash. And idleness and ambition -- the daydream, fantasy roleplaying -- are Eurmal's training for how his grandiose lies get spun.
I'd go out on a limb and say Inora hides some interesting options under her cloak. Cabin fever. Crystal caves. First there is a mountain, then there is no mountain. But there is!
Of course we don't worship her directly.
