Is this some kind of glitch in the Matrix? In the past few years, videos have appeared on the web detailing an unusual but little known phenomenon: rapid light changes over clouds. Scientists actually have no good explanation for this, but a leading hypothesis for its cause has now emerged.  This hypothesis holds that a lightning discharge in a thundercloud nearby can temporarily change the electric field above the cloud where charged ice crystals were reflecting sunlight. The new electric field quickly re-orients the geometric crystals to a new orientation that reflects sunlight differently. In other words, a lightning discharge can cause a sundog to jump. In a few seconds, the old electric field may be restored, causing the ice crystals to return to their original orientation. 

The more you watch this, the creepier it gets.
