Re: Mysterious ball lightning may be brain illusion (May 19, 2010): I was wondering, if the theory is that the eye/mind could be playing tricks on us when we "see" ball lightning, how would that explain the fact that this phenomena is being recorded clearly on video recorders and digital cameras? Shouldn't the effect be the same?

Have you heard about the Brown Mountain Orbs/Lights? A professor from Appalachian State University (Daniel Caton) thinks people are seeing ball lightning on and around Brown Mountain (western North Carolina, the Blue Ridge mountains). The orbs are sometimes seen up close and appear orange. If you Google it, you'll be able to see some of the photos/recordings yourself.
