We ca tell you but there’s techniques to explore the visions and find out .
I always recommend this book to tech you how, it’s a tad involved but the book has guided meditations and tells you how to approach it. You can reopen the dream in a trance state and interact with the elements, go up to the woman and as her who she is etc.
My guess is, this figure is a guide, or someone you knew in a last life.
