hmmm, I see what you mean with Ni. You actually reminded me of my INTJ father, but you were more friendly and outgoing. INTJ's are Ni dominant. I am wondering if infact, your P and J are close. It might help to decifer your Ni / Ne dominance issue.
What stops me from believing that you are a strong INTJ, is that you do not display the "all or nothing" thinking that I have observed in my father. I believe both INTP's and INTJ's desire to ask questions to understand the answers, but both may ask the questions in the way that might not bring forth much Fe tone. (in other words, wording things bluntly at times).
Regarding intuition, do you ever find yourself forming "that funny feeling" because of tangible evidence infront of you, or do you get the feeling moreso with things like Dejavu?
An example: Ni: Myself this evening: (IRL) I had planned to go to Walmart this evening. During the day while I was thinking about it, my one particular friend came to mind and I found myself missing her due to not seeing her in a while. She seemed to be on my mind quite strongly, and I didn't know why I was missing her so profoundly as we had grown apart over a couple of years. It caused me to wonder if I would maybe happen to see her there. Anyway, in the lineup, I looked ahead and saw her mother a couple of people infront of me. So I said "Hello" to her and smiled. I also told her it was neat that I had seen her there, because I had been thinking of her daughter during the day, and actually wondered if I would see her there. She replied that it was actually my friend's birthday today, and she was actually just buying her a card and a gift! So I suppose for me, I wasn't surprised to see my friend's mom at the store, because I had thought of my friend, after I had thought about going to Walmart. (I get this sort of thing all the time), so I am not usually too shocked lol. With Ni, there is a synchronicity and an end to the trail of the flow of events...
Ne I believe, is like forming certain patterns and ideas to form beliefs. Ne is interesting too, because often times it is a correct intuitive outcomes as well. I see it as different though, because it doesn't seem to discover an ending of an outcome of a note of a sequence of events that seem interconnected. It goes continually, and seeks more mystery as it goes on... Ne is attained through seeking out and linking numerous possibilities together with past events, to come up with several theories. It might resemble something like this: A person sees a pair of shoes that they like, which makes them think of an outfit that they have at home that would go perfectly with it. (That favorite outfit was a birthday present from their favorite aunt or something like that.). They go to a store that sells the shoes, but during that time out, they see an item of jewelery that tickles their fancy as well. They go home, get dressed up and go out somewhere. While they are out, they meet someone who just falls in love with their outfit. It's ended up being a topic of conversation, and then there ends up being chemistry etc. If things work out, they can backtrack everything working out perfectly, all because they went to go and buy those particular shoes that day. And, those shoes will always be seen as good luck shoes, yet less potent of a good luck charm, is they are not worn together with the outfit and the jewelery. But they may make a new great set of events, next time they are worn with something else. The shoes really do represent a catalyst of sorts, that got the sequence of events running. To me, it seems a more artistic form of intuition. Ni seems more cut and dry and specific. Plus with Ni there is an end or an outcome that the Ni user senses will happen. This is how I interperate Ni and Ne in situational example form.
Regarding your apparent Ni on your second video that you made, I saw it while you were linking your thoughts and words together. You have a Ti Ni look about you while you are processing information. It strikes me as INTJ. But I also saw some P there as well somehow. It may be in the randomness of how you linked things together, yet somehow it all still fit and made sense in a way that I could follow. I was able to understand where you were going and what you were talking about. So maybe an INTP as well. For me at this point, it's still hard to tell.
Sorry for the long windedness, and I hope my examples were not too strange sounding. Can you liken and relate with anything I have said regarding the two forms of intuition to yourself?
