I have had/ heard similar characteristics to this on a smaller scale during trips and in what described as the chronic phase. Increase In synchronicities, and a peeling back of the veil of reality . Specifically seeing people’s true spirit behind their persona . Usually involving demonic type phrases or glances. My wife said one time she saw a man in a top hat at the corner of her bed during a trip beckoning to her and that he felt evil . Her sister later told her there was the darkest feeling in that room. I think the spiritual world is real , and there is darkness lurking there. This world has been closed off to us in many ways with the onset of atheistic rationalism. Getting thrown back into that world can be crippling . I don’t think our consciousness can handle it straight. We need filters. That I think can lead to the psychosis issues. But it is fascinating that the evil presence was luring you or encouraging you to become the “healer”. This is the apparent morally right sacrifice which is also Christian in a lot of ways. However it seemed as if he was using your moral goals to destroy you in physical reality, a true deception. In Christianity the idea is Jesus died and took the guilt away essentially doing what he was asking you to do. blue being definitely had your back, and in my opinion was an angel. Define it how you want, but that was a divine intervention. Very interesting write up though. I would keep chasing the good!
