Anecdotally, I've seen something sort of similar too. When I was younger, I recall a massive electrical storm that came across our house. The tree against the wall got struck, splitting it in half. I was in the hallway when it happened, and immediately tripped the power out. Though directly after the initial flash that illuminated the whole house, there was this weird echoey persistence of light and sound, and both myself and my Dad could see this ball of light jumping between the light sockets along the roof for several seconds. Sort of the same effect you see when you catch a glimpse of the sun, then blink after and see the persistence of the suns shape in your field of vision. About half a second after each 'jump' it made a really loud crackling sound, and each globe was toast afterwards. It was really strange, and Dad put it down to ball lightning. Though it's not something we often discuss because of the uncertainty around the topic in general. I often dismiss it as one of those 'maybe I remember it wrong because I was so young'.
