I was once standing with my family in our breakfast nook, and a large ball of blue light floated in through the closed kitchen window. It was about the size of a basketball, very bright, kinda sparkly, and it was some sort of electricity, because it made all our hair stand straight up.

It just hovered in the middle of the kitchen for a minute, while my family and I stood there with our mouths hanging open, then it slowly dissipated. We all looked at each other in disbelief, then continued setting the table like nothing had happened.

I'm still not sure what it was. I call it ball lightning, but I really don't know. It was a beautiful sunny day, not stormy at all.
