I've never done it ,but find it interesting. I know a woman whop sees auras - she is such a sweet, kind, shy woman - if it were anybody else I would have been skeptical - but because of her I believe!
She also has pointed things out to myself & others in aura photographs. I still have a hard time with the photography thing (my logical mind getting in the way!) - but I trust her, so I would be very interested in getting it done!
