It's just like Ti to view a perceiving function in a specific, definable term. Ni is not just an ability to predict the future. It is about viewing reality in terms of the underlying patterns, the background feelings of it, the energy behind the motion. Ni is also about attempting to form a sense of the whole of reality. Because of this it has a tendency to make connections in a way different from other functions. It's not a superpower or literally psychic ability.
I actually think it can be both the most accurate and the most erroneous function in terms of intuition. It is willing to take in a bigger spectrum, take bigger risks of insight than a judging function. It doesn't dismiss anything, but simply internalizes the whole of everything encountered. When something is encountered that makes no sense, that doesn't fit anywhere into the internal scheme, it isn't by nature rejected by that specific function, but rather reoriented over and over until it find some place to connect or rest.
So what do you want to hear from a Ni-dom about predictions? Do you want to know if you are going to get a job or a girlfriend you are working towards? Do you want to hear that the reptilians from the Draco system are going to have a final battle with the Greys making all the religions and superstitions throughout history to finally make sense? (too much wine + "Ancient Aliens). I suppose I could predict that we will all die or there will be another sunrise.
This is my prediction: Life will continue to take unexpected turns in both my life and yours. Or perhaps the turns aren't so unexpected as they are events we aren't prepared to face, although we know on some level we must. Life will continue to be difficult, and in some ways hard in exactly the most painful ways for each of us individually as we consciously and sub-consciously work out the scars of our pasts and as we continue to use our broken tools and assumptions to rebuild ourselves in an never ending search to become whole.
