I have a serious question. How do you distinguish between peculiarities of normal sight and actual auras? For example, due to retinal fatigue, staring at any object will create a transparent ‘aura’ around it. This is due to fatigue and the minute constant movements of the eyes which make this ‘imprint’ seem to expand around the object. Retinal fatigue will also produce a colours complementary colour around the object in the same method as above (giving rise to a coloured ‘aura’).
How do you know when you are actually seeing an aura, or just retinal fatigue? Frequent staring at objects and producing this phenomenon causes it to happen much more quickly (conditioning the brain to notice such symptoms much quicker than the ‘default’ setting) – so having them arise instantly (as they do in me) isn’t an indication of one over the other.
I’d be interested to hear from someone versed in auras say how they distinguish between these. I am genuinely interested in this.

Interestingly, I have a possible answer: First of all, I don't see auras like some people report, but in special conditions it happens.
Last night at church (Holy Thursday services) I turned around and saw one girl who seemed to glow. She glowed so impressively that I thought I might be having some sort of eye problem. I turned away and looked at the people sitting in front, back and around her. Nobody had what you could consider a discernible aura- I looked at people until I saw 'afterimages', but nothing that was there already. But when I looked at her, wow! She was on fire! And the thing is she was very plain looking but had the nicest smile. (It wasn't somebody I knew, so I didn't go talk to her.) For the longest time she glowed. Then it was over and everyone left, so I wondered who she was. Now, maybe it was a trick of the light but people next to her didn't glow- I'm still baffled by her. I have to go back tonight for Good Friday Services (I work in the church and my son is going to light the candles in the candlelight ceremony) and I'm going to see if I see her. I'll let you know (if she's there) if she still glows.
