I’m pretty sure you would place this in the imaginary category - subsection dreaming. She would come at night in my sleep.
As for evidence, first I don’t believe in evidence when it comes to spiritual things (not how they work by design), but anyway, I will let you know what I have to that. I have had what one would call frequent wet dreams from puberty to the time I expelled that demon, at about mid to late 30’s, which it quite unusual to have frequent wet dreams continue so long. Most unusual is when I ‘came’, if it was ‘outside’ of her I would wake with the ‘evidence’ of the wet dream, however if it was inside of her there was no evidence that I came, and I was so sure I ejaculated, and usually woke up right after. Like she took it with her.
In the dream I felt her as another entity and not a typical dream character. If you wanted to know the sex actually was quite incredible and enjoyable, but after quite empty. When I started seeking answers for my own life, I found out about this demon and asked her to go. She didn’t want to and instead of the wonderfulness of the sex, it changed to quite a mechanical thing. I would be dreaming and out of nowhere she would appear, come up to me, I would cum inside her, and she would disappear, and I would be left feeling empty, violated and robbed. There was no enjoyment and the ‘moment’ lasted maybe 5 seconds. After I was able to expel her, which is a long story, but basically I challenged her hold over me, her right to me, and claimed the right to break that hold.
After this I noticed a change in my life in regards to romantic relationships.
Up to this I had very few girlfriends and very little sex. So little it was one of those things I questioned as it seemed to come so easy for others to at least the degree that I should have more then I do. After this time I started having g/f’s (and sex) on a much more regular basis to the degree that I consider normal, if not slightly above average. Also some of the holdovers from the early sex did carry through to some amazing sex later once she was gone.
