I do not want to use this thread to discuss the workings of Ni/Se but very briefly and in a super basic manner, I think Ni does a lot of 'tracking' and behavior pattern identification over an often quite long period of time. In the middle, there is the Ti analysis of what is happening and why and Fe is there also picking up on the other person's emotional output to support the Ni and Ti. Ni also uses Se to pick up on concrete but subtle cues and also Se causes the Ni person to eventually act physically or concretely when they think the time is right.
I also sometimes have fuzzy visions of how a situation that is bothering me might play out and I think this might be Ni related. For instance, I used to have these rather somewhat irrational visions of the INTP physically attacking and dominating me. Without judgement of desirability, I think INFJs really are rare and few claiming to be actually are. One way to tell if someone is an INFJ or ENFJ is that issues of power and dominance plays a very important role in their internal life but you would probably never know this as they hardly ever reveal this. I think all Ni/Se people have issues of personal power playing a major role in their internal or external life. Time and right timing does play a huge part in the lives of INFJ and ENFJ types as well. When INFJs explode on people, there is nearly always a lot going on under the surface before the explosion comes and it is almost never really impulsive though to some others who do not understand INFJs it can seem like it came out of nowhere and is just seemingly uncharacteristic of the INFJ overall.
BTW, before that 'crazy' INTP who I actually liked to start with mainly because his insights were always so intelligent, wise and useful, I was a big fan of INTPs and I think I will remain so. I still wonder sometimes if being on the verge of losing his long term job and a few other life changes made him unbalanced.
