I believe evil people do give off an aura, if you will. And sometimes you can sense it. I had a customer years ago when I waited tables. He and his wife and her daughter came in often, but I do not think I had waited on him myself previously. So this day they are at my table. Anyway they are normally behaved and he is polite etc, but I got an overwhelming sense of evil and it was like a horrible wrongness and he just totally creeped me out. There was no outward justification for me to feel that way. Some time later we found out he was arrested for molesting young girls.
Good people give off an aura maybe of a different kind.
Ever since I was a child I would see an aura emanating from a minister when he was preaching a sermon. It didn’t happen every single time but fairly often. I never mentioned it to anyone.
A few years ago a friend was talking about auras and I asked her what she meant. She explained it was Rays of light coming from a persons head and body. I said you mean like the Rays of light that come from. Minister when he is preaching.
She was stunned when I told her I saw them often but only in church. Since I found out what I was seeing, I have not seen one since!
Very much like my experience. There was no external behaviors that gave them away as being dangerous in fact they looked like you could knock them over with a feather but these two were capable of raping and killing a young woman.
