Lightning

God damn.  I don't have any answers for you NightSkye, but as a PSA, don't watch that if you're epileptic 

I am still researching this. This video may have the answer.

I think what I have been seeing is a combination of bead lighting and the flickering aspect of the lighting that happened too fast for me to see anything but the beam of light right in front of me.

He mentions also ball lightning which I also experienced as a child. We were eating dinner. A ball of lightening came down the chimney, rolled across the floor and hit the the living room wall across from the chimney. We were kids. We had no idea what the heck had just happened. Thank goodness, our mother and father, knew what it was. And thank God none of us was hurt and the house did not catch fire.

Still looking for a better example of what I saw.
