Black Mist Charging From A Person

I was almost involved with a man who I consider to be evil. One day we were, for lack of a better word, gazing at one another from about ten feet away. We were both seated. Suddenly, a black mist or smoke or whatever came charging from him barreling straight towards me. I raised my finger and shot it. That was my instinct to break the eye-lock, the moment, and this thing coming directly for me. It worked.

He also claimed to be of Native American Sioux and Cuban descent. He carried a medicine pouch. In it he had some things I had given him and lavender to remind him of his deceased grandmother who had raised him until age five. One of the things I had given him was a "short" rosary. It was a third of a regular rosary. One day I was handling his medicine pouch, but out of respect for him, I never took anything out of it. I use to smell it. On this day, I stuck my hand in it, and felt the rosary. It felt as if he had put playdoh, or tacky-tack,or putty over the cross. I asked him about it and he told me it had been broken.

After some time, I found out he was a complete liar, a probable psychopath, and a really scary dude. I am grateful I did not get involved with him. Any ideas or feelings as to what this mist was? It moved rapidly, and quite frankly, scared me. I never told him I saw it as I was in a great deal of conflict over whether or not I should get involved with this guy. (Attraction/Revulsion) I've searched the net and not found anything that remotely resembles this experience. And why would he cover the crucifix? Is it possible that he was practicing some kind of black magic. He knew I was a good person, and I am afraid his intent was to destroy me. What do you think?
