Footage of rioting in Cairo appears to show a ghost horse and rider. Aladdins Magic Carpet Or The Horseman Of The Apocalypse? I am going with Signal interference or Reflection! But the Synchromysticism aspect is valid!
The ride of the fourth horseman Revelation 6:7-8 tells us this about the fourth seal: "When He opened the fourth seal, I heard the voice of the fourth living creature saying, 'Come and see.' So I looked, and behold, a pale horse. And the name of him who sat on it was Death, and Hades followed with him."
The Expositor's Bible Commentary says this about the color of the fourth horse: "'Pale' (chloros) denotes a yellowish green, the light green of a plant, or the paleness of a sick person in contrast to a healthy appearance." Put bluntly, this horse is the color of death.
