Who is she?

My friend told me a surprising thing lately. A spirit has been visiting him since he was little.she is beautiful and warm.half naked. of course he called her mother.Now she is much more than mother and appeared much more times .he couldnt have a normal relationship.because all he wants and seeks is her.he tried to find girls looklike her... besides.he is having other health problems lately....but he doesnt believe its from her. he believes she is either a goddess or ancestor or spirit guide.

I asked a few others. some also say yes. how could it possible a goddess or ancestor spirit guide do such a thing ?

I m trying to talk to her.but its hard.she hides very deeply.
If she is succubus that would be dangerous.

What's ur thoughts?
