I was on a Discord chatroom back in December of last year and met someone who claimed that she was a lich (accomplished using a phylactery), and she had quite a following of prospective "souls" and "members" in her circle. What she was trying to do with these people thousands of miles away I don't know, but something a bit spooky came of it after I left. I felt a tremendous amount of what I could only describe as dark energy. It was hungry, trying to seep into and infiltrate my thoughts and what I can best term as my "energetic body / presence." I think it wanted to teach me the allure of its feeling-tone, because that energy, despite trying to ward it off and rebuke it, my body was not lying to me that it had an element of satisfaction to it.
To make things stranger, that night I had a vivid dream, at the end of which I was caught in this weird dark tunnel pulling me endlessly down, complete with the same dark energy feeling-tone. I felt this strong buzzing sensation too, and a bright angel appeared from beyond the wall of the tunnel and said, "You have been cursed! Get out of here now!"
After going through that, while in the original Discord server that she found me in - a den of wolves and vipers I'm sure - a christian joined, went straight to me to message me privately, and said that Jesus was looking for me (what a trooper and a man of faith!). There, I turned myself over to Him again, as far as I could possibly surrender honestly, trying to surrender within me what I still struggle with now. Thanks in part to this experience (knowing what is good by experiencing what is not) perhaps I am more aware of my "life energy" now. But it hasn't been an easy ride, I've experienced plenty of that same / similar negative energy from within since because of resentment for an unhappy childhood.
