Hello Fiiish. I'm glad you are mentioning this.
If a thought pop up in your head and you see it happen soon after, then there is no doupt it is Pre-cognition.
Why? Because manifested intention needs focus. The creative energy are gathered around a thought when it is focused; a maintained focus with the emotive charge it needs to fuel it. You need to charge your thought with creative energy in order to see it becoming reality.
If you catch a thought of something that will manifest soon after, it is simply because we are transmiter-receiver. Your mind caught the creative energy at work. But it might also not happen at all, because the creative energy is dynamic, it is always in movement, simply because the mass consciousness is always evolving/changing. That is why it happens rarely.
If someone catch a focus in gestation, being collective or individual, being conscious or unconscious, and tells it to others in a prediction form, and the others begging to believe it, to focus on it. Their focus adds to the creative formation of energy and it come closer to being manifested. On the other hand, if enough people focus on an opposite thought including the same elements concerned, than the creative energy answer to these focus and the prediction might not happen or happens but in a different manner.
We have different focus, but use the same creative energy. This is why it adds to the complexity of making predictions.
Hope it helped.
Namaste, Steven
