Nobody knows what these types of energetic phenomenon are, but we do know that the Scientism religion will step in and try to either explain it away with fancy words or ignore it.

This is not an unusual phenomenon. I grew up in the Czech Republic in the Krkonoše near town Jičín, and ball lightning was very common here. Different sizes. Largest I saw had a diameter of about 1.5 m (but was more yellow color). They most often appear before a storm and can pass through a keyhole and then enlarge again.

Thank you.
