Call them crazy, but there are some people who claim to see luminous colors or glowing light surrounding other people. Most scientists deny the existence of a visible human energy field, chalking it up to psychic poppycock or an unusual form of synesthesia. But at least one recent discovery should make even the most skeptical researcher take pause. Japanese scientists have shown that the human body actually does emit small amounts of visible light. In other words, we literally glow throughout the day and night, fluctuating in intensity. Though this light is apparently too weak to be detected by the human eye, still, you have to wonder ... could a few hypersensitive individuals really be aura-seers?
