Good questions! I need to read further the link on Ball Lightning, but from my first persusal it said that "Ball Lightning/Globe Lightning" is redish in color and floats in the air. It has been reported a certain size and travels at a certain pace. The white opaque light formation I saw, was a soft white glowball...very smoothing to the eye. When I first saw it I was standing at my bedroom window looking out into the yard at night. The glowball appeared from somewhere acting like it was playing "dancing" while traveling slowly over my yard below. It was the size of about a "basketball". When I asked my sister who was with me "What the heck is that?" (She saw it, and til this day stands by what she saw.) The glowball then darted up about six feet in the air as if it heard me. I said, "It can hear us, it can see us, it is coming over here!". My sister screamed and fell to the floor behind me. I looked at her and then back out to the yard and saw nothing where it was before. Then the glowball slowly came up from beneath my window to show itself in full view in front of me. It was now the size of a "hula-hoop". I believe this experience, the glowball, was intelligent in being because of what I felt going on inside my chest while looking into it. I first felt a grand emotion of "Joy and Love", followed by a butterfly feeling in my chest, followed by three thumps. Each thump harder than the one before". I finally waved and said "Hi!" to it and it tore out of my chest and flew across the street over a rooftop, leaving me with an endless emotion of "Loss and Sorrow". I will try and study up on Ball Lightning to see if it "changes size, is white, and moves with what I call intelligence". Since this experience, I believe I am somehow connected to two worlds, the one here and the one in my head which is an "after effect" of the glowball's impact on my life. No need to go there because no one will understand it anyway. For now, though I'll do some research on Ball Lightning. Aren't those crop circles beautiful? Thanks, Leah
