SA-XHBK,
Many years ago, I experienced some similar things to those you described, and used them as the basis for some prayer experiments. I used the Bible as a source of materials and methods, got prayers to try from there, and prayed, or didn't pray, for various encounters. The whole experience convinced me that the world is haunted, and that the haunts, or demons, were obsessive, nasty buggers. They'd get a bee in the bonnet to create trouble in a certain way or place, and unless you got rid of them, that's what would happen.
Sounds like you are in a unique position to learn something about how the world is really put together. You should take advantage of it.
By the way, you are probably lucky that the girls that get nasty around you are showing their true colors. Maybe your mother is praying for you. You know the song, right? "My momma done told me...." too, too true. It's not exactly the girls' fault, though. According to the tales of scripture, demons prefer to pick on women, to get them to cause men to throw both their lives away. To be on the safe side, it's best to try to hang out with women who are strongly attached to a father figure. You have to make friends with him, too, but that can be a good thing. Until you get the spooks thing figured out, this is the only safe way to go with women.
Cheers,
Stephen
