Last one on vid=possible ball lightening.
Not saying that that is what it is, but i am sure that anyone that has any credentials is going to shrug it off as being such.
I've seen the exact same "orbs" during similar thunderstorms (ones that are off in the distance and the whole cloud glows from the energy within).
All I can do is tell you stories, wish I had video evidence of the stuff I've seen!
One account from my family was when they were children on the farm in the 1950's, my grandmother had the rear and front doors open in the house on a spring day to air out the farm house.
My father comes from a family of 10 kids, and he and his younger sisters remember an "orb" of light coming down from the sky and they watched it go through the back door of the house, bounce around on the floor, and exit through the front door and go back up into the sky.
