I need help to find the creature or character or tale or whatever linked to the following description:
Have a connection:
With dreams, like maybe as a bridge.
With secrets or maybe contracts? Or the notion of using words with intentions.
With music or rhythm or singing.
With energies or spirits or souls, like being able to feel energies, move it within someone by touching (like getting rid of heavy energies to help), or seeing someone's .. huh soul... place?
There is also a connection to water and clairvoyance and it might be something or someone with a mention of something on their back.
And something to do with keys as well, opening doors (but that might just be the bridge thing mentioned earlier).
As to location, I'd say maybe from Africa or India? Or around the Indian Ocean. Any clue from anywhere would be amazing to be honest.
I don't know all details so there might be details missing.
Edit from comment - I did some intense search before finally finding Mythology and Folklore and read about Hekate and also Seiðr, and despite both being really close (especially Seiðr), I feel like there is something missing to it but couldn't cross reference any of those with other existing myths and legends, I thought "maybe some kind of shapeshifter".
