Is it all in your head?
It’s a weather phenomenon that has puzzled the minds of scientists for thousands of years. As far back as the ancient Greeks, there have been eyewitness accounts of floating, glowing balls of electricity emerging after a thunderstorm. These balls of energy have ranged from the size of a golf ball to a few metres wide. There have even been reports of the plasma-like balls floating in the sky and entering people’s homes before vanishing.
