Superman: Action Comics: Phantoms

Each time I think I've made a connection with someone... once they find out what I can do, whether it's hours or days later, everything changes. Invariably they freak. They get retroactively paranoid, wondering what else Clark Kent is hiding from them.

I can see this, I suppose you could call it, aura of colors that words can't describe around living things. And when something dies the aura fades leaving something that's not easy to look at. It appears empty in a way that makes you feel empty too!
