Don't really think we've developed such an advanced ability yet, although something like it might be possible in theory. It's like suddenly gaining the ability to perform photosynthesis with your skin and hair. Awesome, and with something like that there's probably enough necessity around for it to develop after many millions and millions of years, but it's too huge of a change to have developed suddenly, and too useful to only exist in a few people. I'm not actually sure if the photosynthesis thing is possible or if something would interfere, but now I want to devote my life to making it so with genetic engineering. Bulbasaur!
But yeah, it sounds like a useful subconscious tool that your mind developed to organize data. One that I wish I had. But not aura reading.
