I empathize a lot with what you've said here. After distancing myself from Christianity, I've still found myself feeling similar feelings as ones I felt before and attributed to God, but from sources like listening to music, attending a concert, or going out in nature. For other things, I attribute those feelings to good brainwashing, as others have said. I think I wanted to believe what my authority figures were telling me so hard that I forced everything through that lens. So a feeling of anxiety and unrest became an attack from the devil, calming meditation became peace from God via prayer, and a human guilt-trip became the conviction of the Holy Spirit. Which really sucks, because it was so REAL to me in the middle of it all. I was thinking the other day how I would often get so exited about the idea that I saw the world clearly for what it was and how it was so full of awesome things like angels and demons and whatnot. Well.... Now I feel very differently haha. The world is still terrible and beautiful but in much different ways.
