Swapneshwari, Literally translated to "Dream Lord/Lady", she is petitioned for dreams of prophecy, advice, visions of deities, and I imagine probably willing to help with insomnia and night terrors.

Clues point to being treated as an emanation of Durga. Probably due to her very narrow (but very cool) role; Swapneshwari has no temples dedicated to her and very little in the way of iconography. Which of course means I have to/get to do everything myself!

Being associated with the mind the fog of sleep and illuminated rainbow were an easy choice for a platform. Her crown is moon-crested and dress embroidered with the night sky for the obvious fact most sleep during the night. She carries a dream-catcher because duh and a crystal ball for her scrying duty. The drum and beads represent the meditational and trance practice one may undergo for dream control.

She seems under appreciated. Maybe sleeping doesn't seem like a big domain to lord over but remember that you spend a third of your life doing it.
