Clairvoyance or something...?

Hi everyone,

I am currently reading The Celestine Prophecy and thus I exercise and experimtent a bit with clairvoyance and energy work.
I had already tried to see the human aura some time ago(started with this beholding the fingers in front of a white background exercise) and over the years, sometimes randomly sometimes by will, I could see something. The probably most impressive result was, that especially during karate class when I was a bit exhausted, I could see a round, solid and colorless shape above the head of the other guys when they were walking in front of the white wall.
At first I had thought, that this could be the Crown Chakra or so, but I found out quickly that I could see this shape also above lifeless objects, for example the roof of buildings when they were in front of the sky.
Right now, I wonder if this round shape above and sometimes around objects could be a common phenomenon, maybe caused by a weary eye or if it has something to do with clairvoynce.
Does somebody here know what this could be and, if it is really clairvoyance, how I could enhance it up to a practical use??

Thanks for your help,
Sarem 8-)

Diabetes and glaucoma are the big potential medical causes. It might be worth getting some air shot at your eyes just to make sure. But it probably has more to do with an altered state of consciousness, and I must say that a lot of very useful information can come from the feel or aura of a building. Events leave perceptible traces in places.
