Plasmic Sphere Of Greenish Blue Light.

I was extremly young, maby five years of age, and had the habit of sneaking out into the yard in the middle of the night, just to be Surrounded by Natural things. I was in the back yard laying in the grass, and out of the corner of My eye, saw somthing very bright. Istood up, and approximatly three feet from My Face was a Plasmic Sphere of Greenish Blue Light. This was much like the 'Glass plasma Balls' that change their Patterns while switched on, that One can purchase at science/ hobby stores, but bigger,and Brighter. This must have had a stattic 'charge of some sourt because as I Would try to Touch This, It would move away from My Hand. If I stood still, this would stay about three feet from my face. My guess as to What this was at this point in time,is 'Ball lightning'. This had occured in the Sonora reagion of California. I had thought that this was one of the Coolest things that I had seen,and still think that this was cool.
