I never had any problems with Demons. In fact, I never had any experiences with Demons. I have had minor events that I could explain with science--usually minor "hallucinations" that happen if I am drifting to sleep and get awoken (those are actually more like dreams than hallucinations, and nothing to worry about). The witlesses have, however, threatened Demon attacks. I have heard that Demons lurk in disaster scenes like fires and such, and that I could be attacked by Father Satan if I thought about Him too much (what an insult).
As for being bothered by angels, that's another matter. Joke-hova itself set me up to be dragged into the cancer in the first place, and then the filthy angels got together and sealed my dedication to joke-hova using magick principles including the 9-fold affirmation. Ever since then, once I got baptized everything seemed lifeless. Field circus was a burden and drudgery, not a joy. And they wanted me to do it all the time, pious-sneering (would have been even worse a drudgery).
