It's rare for me to actually have an attack, but this is also the first time I've been attacked by someone else's stuff and not by own stuff.
I also know from experience with channeling, that wasn't poetry. It wasn't about art. It looks like poetry because the person is being puffed up and they're basically getting a big rush from dramatizing experiences and want to prove to everyone that they are, basically, some kind of earth angel or Christ-sent superhero on a mission. Some made sense and is agreeable but other parts didn't make sense because that person is probably experiencing some form of psychosis.
This kind of demonic oppression will make you a proud spiritual narcissist - boasting in yourself and not of Christ, thinking you have the power to overcome Satan and all of the demons because you believe YOU are the "light", and they've probably worked out enough spiritual experiences to trick the person into putting themselves under attack daily, because they think it's their "job." (Hence the mentioning summoning Satan himself part in order to attack and defeat him.)
So the reason I fell under attack is probably because I recognized it and saw the familiarities from having been there myself from converting from witch to Christian. That's something God spent years taking me out of.
One verse stuck out to me at that time: "For God hath not given us the spirit of fear; but of power, and of love, and of a sound mind."
That's what pulled me out of it. Hope Dark Psalmist gets a chance to read this part, because understanding of what is actually happening could be a good awakening.
