After reading everyone's thoughts, they are probably all correct.
The halo effect (white light) with the blue line, is something I have seen since my late 20's.
It was at a church celebration of some sort, and it was the priest's which got my attention. However most people that I have seen, present with similar, though some are a little larger, than others.
The chakras can be felt, energy wise and the energy field seen around the head also extends around the body in some people - either that or I am unable to see the energy of some people.
Unable to see the aura and its colours at this time...
