Also the subject of auras may also be of interest to some posting in this thread.

I've only seen an aura two times.

Scary and fascinating!

See this site Auras for an introduction to the subject.

Here is a quote from that site:

"An aura is the electromagnetic field surrounding an object. Some people refer to this field as a bio-energy field.

In truth this energy field not only goes around you, but moves within your body as well. It is not just the outside of your body that is made of electromagnetic energies, every part of your and everything your experience in third dimension.

Auras vibrate to different color, sound and light frequencies. The color spectrum varies with one's physical, emotional, mental, and spiritual states."
