I find psychic vampires very interesting. I once dated one without knowing it. After he began to fully trust me he told me he was one, and described to me how he often drained people's energy without knowing it; the only way he would know is if people started feeling really dizzy around him for no reason or get irritable after standing by him for a few minutes, even though he wouldn't say/do anything. I have had felt faint around him a few times, and when I had a weird feeling right before my first vision (it felt like someone had stabbed me in between my eyebrows, and I could have sworn I felt blood rolling down my face - but when I touched my face, nothing was there) he said he was resisting from draining me. I hadn't understand, since he didn't seem to have had a problem before, but he said it was because my energy seemed to have escalated to great lengths.
Now I've noticed similar instances around another guy-friend of mine; when we first started hanging out together, I would get tired and irritable after about 10-20 minutes, maybe half an hour - but we would just be watching TV or I would be having a great time. One day I spent three hours with him, and I was absolutely exhausted by the time I got home, so much so that I slept for half of the next day. I've watched his friends around him - when we first went to his group of friends, he was tired while everyone else was bubbling with joy. About twenty minutes later, their moods were completely the other way around, with his friends acting lethargic and him bouncing off the walls.
Although, it seems to have almost passed with me - it takes at least two and a half hours for the tired feeling to come, as if I'm used to it. His best friend is completely immune to it (they spend a LOT of time together) and our other friend is the same way I first was with him.
So, does anyone think he could be a psychic vampire? And can anyone give me more information on them? Thanks!
