I generally see blue/gold around people's heads - but that's usually when I'm watching someone lecturing or giving a speech, so makes sense.

I've seen it in the theatre too and also seen spirits behind the people acting (just like a black outline).

I got really angry at a meeting last year. I wasn't controlling my anger and another person said that they could almost feel the air crackling around me as well as directed to the person (is that what you mean by energy fields punkin?)
