++"How can you tell if someone is astral projecting on you?"
Usually by the smell.
... wait. I think maybe I don't know what "astral" means.
+"Sometimes I would make comments about him in the car (because he was a very angry, controlling man) and inside me could "feel" that he knew and was upset about it. When I would see him a few minutes later, he wouldn't talk to me or even look at me and acted angry."
I fail to see how someone you describe as angry having an angry demeanor and ignoring you is proof of anything. At best, it proves that he's angry and doesn't see you as important enough to go out of his way to acknowledge every time he sees you. You're rather self-important for a self-proclaimed servant, don't you think?
++'He would say things from the pulpit that had to do with what I had said."
So the person you were going to see said things that had something to do with what you said? That would be an amazing coincidence if not for the fact that by all appearances your comments were prompted by a combination of his personality and what you were going to see him for, which would be the primary motivators of his own words.
You might also keep in mind that you and/or your friends consider this many to be a holy representative of your god. When you talk shit abut him there's a very good chance that any faithful little pets will happily repeat every word of it (and then some) in hopes of getting a pat on the head.
You might also keep in mind that you were already looking for such similarities. If you go looking for a pattern in the abstract, you'll find it.
++"I would also be attacked by demons at that church and after church at home during that time as well. "
How convenient that what should have been the more solid proof of your assertions just so happens to take place in an invisible manner at the hands of invisible beings. That didn't work on your mother when she caught you with your hand in the cookie jar and it won't work now.
++"He was a very manipulative man and highly intelligent. He would plant negative thoughts in people's heads about other people in the church"
If only you were smart enough to understand that you just offered further proof that this is all in your head.
++"He was very legalistic."
What the fuck does that have to do with anything? Contrary to what you'll hear from most comedians, lawyers aren't actually[I/] in league with the devil.
Most of the time.
++"Can anyone give me insight on this?"
You're fucking insane and rush to attribute the simplest things to some convoluted ploy by a cabal of invisible beings to levy a protracted assault upon you for no good reason. Which means you're also probably a bit of a narcissist but that's the least of your problems at the moment.
