That would explain that strange experience I had several years ago. This girl walked up to me in a bar and said I want to have your babies. We went back to my place and had wild uncontrollable sex. After the night was over she left (presumably pregnant) and I haven’t seen her since. It was as though she vanished into thin air, or completed her task by getting pregnant, and returned through the portal to another dimension
and you "know" this because? sorry but the unknown is UNKNOWN and owes nothing to what people tell each other, even if they did carve it in stone or claim it to have come from on high. demon is a pajorative euphamism humans have pulled out of their ass. not that there's anything to stop there from being un-nice unseen things just as there can just as easily be nice and mostly neutral ones. but so called "knowledge" of the unknown, is essentially blowing smoke.
