I have a few thoughts about what might make your visionary Ni realizations process work:
1. Many mystics say things like, "you attract all events in your life", or "your focus determines your reality" and such, but I've never known how literally to take those radical beliefs.
2. Some philosophers (like Nietzsche or Spinoza) make claims like, "the will is a force and a world mover", or that "the will of God is the prime cause", making it a potential 'will to action'.
3. All of our knowledge has its origins in our perceptions. Perhaps they way you are 'seeing' the world influences the way it will be shaped (this combines the first 2 principles outlined).
