I believe Washington's vision is real. It certainly has come true. That's the litmus test. Reality. Here is the 3rd vision, where we are now.

"And again I heard the mysterious voice saying "Son of the Republic, look and learn." At this the dark, shadowy angel placed a trumpet to his mouth, and blew three distinct blasts; and taking water from the ocean, he sprinkled it upon Europe, Asia and Africa. Then my eyes beheld a fearful scene: From each of these countries arose thick, black clouds that were soon joined into one. Throughout this mass there gleamed a dark red light by which I saw hordes of armed men, who, moving with the cloud, marched by land and sailed by sea to America. Our country was enveloped in this volume of cloud, and I saw these vast armies devastate the whole county and burn the villages, towns and cities that I beheld springing up. As my ears listened to the thundering of the cannon, clashing of sword, and the shouts and cries of millions in mortal combat, I heard again the mysterious voice saying, "Son of the Republic, look and learn" When the voice had ceased, the dark shadowy angel placed his trumpet once more to his mouth, and blew a long and fearful blast. "Instantly a light as of a thousand suns shone down from above me, and pierced and broke into fragments the dark cloud which enveloped America. At the same moment the angel upon whose head still shone the word Union, and who bore our national flag in one hand and a sword in the other, descended from the heavens attended by legions of white spirits. These immediately joined the inhabitants of America, who I perceived were will nigh overcome, but who immediately taking courage again, closed up their broken ranks and renewed the battle.
Again, amid the fearful noise of the conflict, I heard the mysterious voice saying, "Son of the Republic, look and learn." As the voice ceased, the shadowy angel for the last time dipped water from the ocean and sprinkled it upon America. Instantly the dark cloud rolled back, together with the armies it had brought, leaving the inhabitants of the land victorious!
Then once more I beheld the villages, towns and cities springing up where I had seen them before, while the bright angel, planting the azure standard he had brought in the midst of them, cried with a loud voice: "While the stars remain, and the heavens send down dew upon the earth, so long shall the Union last." And taking from his brow the crown on which blazoned the word "Union," he placed it upon the Standard while the people, kneeling down, said, "Amen."
