I had one of those Ni moments, and something occurred to me...
Depending on who you ask, the shadow mode for INFJ is ENFP or ESTP. The assumption here is that when the mind reaches a point where it isn't successful, it begins to attempt to adapt by changing its approach.
Beebe's theory is that our shadow functions are the inverse of our normal functions. INFJs go from Ni > Fe > Ti > Se to Ne > Fi > Te > Si. The assumption is that the mind switches polarity from introverted > extroverted to extroverted > introverted but attempts to retain the same process order - N > F > T > S.
The other theory suggests that the mind simply reverese cognitive function order as a response to stress. In this theory, INFJs go from Ni > Fe > Ti > Se to Se > Ti > Fe > Ni. From what I've seen in myself, this is my extremely stressed mode, my life or death survival mode.
Both of these modes occur when an individual is under stress, but the latter is the result of more severe stress.
But, what I realized is that the second theory is actually wrong in how it describes what is happening. Beebe's theory is correct in both instances, but if stress is high enough also switches processes - S > T > F > N - as a further adaptive reaction to stress. It's not a reversal. It's a complete inversion.
While this seems like another of my knit picking posts about the inner workings of all of this, it isn't. This is a huge induction, because it proves that cognitive functions are fluid, and not static. For the following to occur, this means the mind scales across the introverted and extroverted axis, most likely in proportion to stress.
Ni > Fe > Ti > Se
Ne > Fi > Te > Si
The reason these are called shadow functions, and that they have the effect on us that they do is because we tend to only used them when forced... until we've used them often enough to begin to see the benefit of them rather than the hinderances.
For example, for INFJs, the Sennex function is Fi. The reason Fi has the effects associated with the Sennex on us ...

makes me confuse about being an INFJ
