Anything that is happening within the scope of time is not real. What you are seeing in your life at this very hour is not what is actual happening now, you are only seeing the after effect of choices and decisions which your spirit has already taken in the spirit world. What you call day to day life, your spirit calls the past. Earthly life is actually reliving spiritual life and things which your spirit has already experienced in eternity. What you call reality is nothing but an illusion. The reason people get night dreams and they come to pass, is because their spirits revealed to their minds what had transpired in the spirit world.
The prophet Daniel had been fasting and praying for 21 days concerning a troubling vision which he had seen ( Daniel 10:1). In response to his prayer, God sent Angel Gabriel to explain the vision to him. However, the Angel was arrested in the second heaven by the Prince of Persia. The prince of Persia was demonic force which Satan had set over the Kingdom of Persia, he ruled the Kingdom from the realm of the spirit. The Earthly Kingdom of Persia was ruled by a human King, but in the realm of the spirit, there was a chief demon who manipulated and controlled things. Whatever happened in Persia was already decided in the realm of the spirit, the Bible further reveals that after Angel Michael defeated the spiritual force behind Persia, the Earthly Kingdom later collapsed. Alexandra the great later came on the scene and conquered the Earthly Kingdom of Persia.
