I found this link to the vision online:
Night of the Red Sky
Native American Metis Prophesy
The Prophetic Visions of 'Grandfather'
from Tom Brown Jr.
In the 1920s, an Apache wise man had a Vision of four prophecies that foretold death and destruction for mankind, unless we incorporate Spirit in our daily lives.
Two of these prophecies may already have come true.
A number of people can predict the future, but few get the timing correct. "Grandfather" was an Apache wise man and scout, named Stalking Wolf, who grew up outside white man's influence. His many predictions not only came true in the manner he predicted, but also when he predicted.
Tom Brown, Jr. learned extensively from Grandfather for twenty years, from their first meeting when Tom was seven years old. Stalking Wolf was the real-life grandfather of Tom's best friend at the time. The following excerpt from Tom's book, The Quest, tells of Grandfather's predictions for all of mankind.
Looking back, I can clearly see that Grandfather's prophecies, unlike anything else, had the greatest influence on my life. At the time they had little more effect than to frighten me and cause me to sit up and take notice. It wasn't until after his prophecies began to come true that their haunting impact began to affect me in a very profound way.
More than any other person-prophet, religious leader or psychic-I have ever met, Grandfather's prophecies, on both a major and a minor scale, came true exactly at the time he prophesied and exactly as he prophesied. With that record, I could not help but feel the impact of these prophecies on my life.
Grandfather could foretell the future with tremendous accuracy. Not only could he precisely tell us what would happen in the next moment, day, week or year, but with the same accuracy he could predict the possible futures for ten years and more away. It was not long before I began to keep detailed records of his predictions, along with other notes I kept on survival skills, tracking, awareness and things of the Spirit. I received from Grandfather hundreds of personal, minor predictions, and well over half have since come true. Along with the minor personal prophecies was a list of 103 major predictions, of which, to date, over 65 have become absolutely true, not only in time and place but also in the exact order in which they were predicted to happen.
Grandfather said that there was not future, only possible futures. The 'now' was like the palm of a hand, with each finger being the possible future, and, as always, one of the futures was always the most powerful, the way that the main course of events would surely take us. Thus his predictions were of the possible future, which meant that he always left a choice.
"If a man could make the right choices," he said, "then he could significantly alter the course of the possible future. No man, then, should feel insignificant, for it only takes one man to alter the consciousness of mankind through the Spirit-that-moves-in-all-things. In essence, one thought influences another, then another, until the thought is made manifest throughout all of Creation. It is the same thought, the same force, that causes an entire flock of birds to change course, as the flock then has one mind."
Out of all the personal and major prophecies that Grandfather foretold, there are four that stand out above all the rest. It is these four that mark the destruction of man and life on Earth, as we know it to exist now. Yet Grandfather said that we could still change things, even after the first two prophecies came true, but that there could be no turning back after the third.
Now that we have gone well past the second prophecy, danger and destruction are very apparent, and our only recourse is to work harder to change what has possibly become the inevitable. The urgency that I feel-now, more than ever-is a direct result of the second, impossible prophecy coming true. It is the reason that I teach, sometimes with a certain desperation, and constantly with the sense that we are quickly running out of time.
I should have worked harder and with that same desperation at a much earlier date, but, like the rest of mankind, it took a strong message to get me motivated. I should have known that these things he prophesied would some day come true, because his personal, minor predictions were coming true daily.
He so accurately foretold of Rick's death on a white horse, that I would some day teach, that I would have a son-and that taking him into the Pine Barrens for the first time would forever change my life. He predicted the formation of my school, my books, my family, and even the horrible mistakes I would make as I tried to live within society.
