Phenom Lightning

Can you give me some info on ball lightning and if there has been any studies connecting it with combustion?
I know that this may seem like a stretch. But spontaneous human combustion is a heavily debated phenom. It is almost as controversial as ball lightning. From the little that I know ball lightning has been known to pass through planes and walls. Now if a person was standing there and ball lighning attempted to pass through them, wouldn’t this be a valid theory for the cause of spontaneous human combustion. Any links or research into this topic would be welcome.
I wouldn’t know about SHC or ball lightning passing through objects (maybe some kind of quantum tunneling, forget I said that), my personal guess is that ball lightning is an incandescent piece of aerogel.
