I think that I was offered to be taught necromancy by a wraith- not sure if he was one, but he was a skeleton cloaked in a black cloak. He was quite short, a bit shorter than me. I saw it with my mind's eye and it was so clear, but I'm still not sure if it was my imagination or what not. Long story short, I accepted, became terrified (he had so much power!) without actually communicating with him and felt his presence beside my bed. Coming from a family where some of my ancestors are with the 'gift', I have a tendency to see spirits very clearly with my physical eyes (but only in glimpses, but they appear to be solid). So....what did I do? I tried to eat him. I literally tried to eat him.
I imagined a bubble surrounding him and sort of engulfing him (I read about it somewhere on another forum) but I could never 'finish him off' cleanly, like you would lick a plate clean, to be more morbid. No, he was still there and I went about my daily life ignoring him. A few months afterwards, when I was entering into my bedroom, I saw a hooded figure, much more diminished in its energy. I wasn't scared. Just wary. I walked out immediately.
Eventually, I spewed off that energy and gave it back to him- directed it to him in my mind. I still feel as though he kept tabs on me afterwards for a while then stopped. But luckily, I don't think he was offended- I think that he was just seriously observing the effects on me as a human being from all that excessive dark energy I absorbed. Looking back, I find my reaction a bit comical, but it was nevertheless, absolutely scary at the time of the encounter. And guess what? The wraith had the name of a flower
