Is Ni information you subconciously take in via Se?

[PikUpYourPantsPatrol]

Sometimes an idea will randomly pop into my head and I later figure out something triggered it. For example if I leave a page open in a book or something and then later find out that's what I was thinking about, this has happened a lot with other examples that are hard to describe, is it just coincidental?

Se and Ni are opposites, just like Ti-Fe, Fi-Te, and Si-Ne.
Introverted intuition is the perception of time, recognizing trends through memory and anticipating the future. Extroverted sensing is simply an awareness of surroundings, and realizing how something impacts the present reality.
I am not sure if they are coincidental or not, but the example you described sounds most like Ni.
