I have that to a small degree. I've always put it as... I can see deep into one's heart, and see what they really are. But I would love to delve into that to get some auras ( my astigmatism, gives me auras for street lights.. how about some for people?
hehe). Basically if someone says they are evil, or good, or whatever, I can see it regardless. My proof (which would be by personal experience) is from a friend who.. although seemed like a good guy, was constantly plauged by satan, and he himself was unsure of where he stood, and even asked me why I persued to be his friend, when all that stuff was within him... I've also noticed that small bit that I can notice is right almost all the time. The problem is that I can't tell if they're sneaky bastards, or stealers, or people with bad tempers. Heck, or people who cheat. But hey, I got something, and I'm happy with that.
