Well, I have very good "telepathy" with loved ones, like knowing people need me or that they're trying to contact me or even that they're standing behind me. I can feel that someone I'm already close to may come back into my life.
But I am terrible at jumping to wrong conclusions. Like seriously, I can think this or that and have it be totally wrong. I made two very bad guesses about another person and myself just this past week. I've also mixed up my own vision/desires with what I thought was intuition.
I think this is a sign my Ni is tertiary not in any way dom/aux. I don't think I'm Ne, either, because I seriously don't sit around and think about absurd hypotheticals and I can get really frustrated when someone insists on their theory being correct when it clearly doesn't have jack shit to do with real life. However, I am "random" and "big picture"...and guess what? Se is random and big picture too, and Se types frequently mistype as Ns, especially ISxPs.
Also, when I was in my teens my Ni felt very "mysterious" and "supernatural" to me, which is apparently common in Se types more than true NFs, especially INFJ who has Ni as a dom function wouldn't see their Ni as "mysterious." I even had an INTJ say the other day on this forum in a thread that his Ni isn't all that mysterious.
I know this doesn't apply if you're an ISFJ, in fact if you were ISFJ you would reject Ne, so you might want to ask someone like Giggly, or even EJCC (an ESTJ who has well developed Ne, ESxJs do more often, my ESFJ ex did, and my ISTPs ESFJ mommy is about 50 and her current age uses Ne with such dexterity it just confirmed to me that she has more Ne than I do!)
