The brain is certainly capable of far more than we (currently) can understand scientifically. Some of us have gifts which are definitely NOT explicable by current knowledge-base. I have no reason to suppose that auras or whatever are outside this possibility, but have had no experience of such things either 1st or 3rd hand (other than on boards like this) - in other words I have never actually experienced anyone seeing an aura. I have experienced the effects of black magic though.... and of healing hands.
