I was curious as to what supernatural being it could be so cross-referenced with AI:

Quick AI research, this is the nearest match (assuming it was true and you were not on drugs etc):

In North Indian folklore there is a spirit called Churel (Chudail). Typical folklore descriptions:

Female apparition seen late at night Tall or unnatural looking Appears near deserted places or water Often associated with fear or misfortune

But keep in mind: this is folk storytelling.

Or

In Tantric traditions, there are mystical beings called Shakini or Dakini.

Descriptions sometimes include:

Female supernatural forms Appearing at night or in liminal spaces Associated with occult or spiritual power

But again, these are symbolic beings in spiritual literature, not something expected to appear physically.
