I had a girlfriend long ago who said she saw auras. Since she also believed in the efficacy of tarot and several other seeming delusions, I paid little attention. More recently, I've heard the suggestion that people who see "auras" are actually seeing a colour or two into the ultraviolet.
I understand that there *are* people who can see into the ultraviolet. Does anyone know if anyone has compared the descriptions that test subjects provide of what they're seeing with the descriptions that aura-seers report? Are there other plausible explanations for what these people say they're seeing? And any pointers to subject descriptions of UV colors?
Is there any evidence of any humans who can perceive other non-visible
EM wavelengths (besides coarse sensing of IR)?
What uses are there for non-visible EM imaging of human bodies (besides
x-rays)? Say, is IR human imaging useful in medicine, or can it be used
to estimate someone's emotional state?

Is there any useful way to feed a broader spectrum into the brain other than mapping it into the currently-visible spectrum and using the optic machinery?
