I recently started thinking about this, but forgive me if this is obvious or already covered (somewhere...)
I know that we have a shadow, that we can act on under stress - in my case, I am an INFJ, so my shadow is ESTP. Basically all the cognitive functions I have from dominant to inferior are reversed, making my weak Se controlling.
On the other hand, our shadow functions, the ones we tend to not use, we can be attracted to - in my case, Ne, Fi, Te, and Si are my opposite functions. This is the four functional preferences of the ENFP, which by MBTI is considered compatible with INFJ.
But I'm not talking about relationship compatibility, but more our certain desire to be like what we want. I don't know if that makes sense, but here's how I understand it: when I'm in a good mood, I can be pretty silly and ENFP-ish. Talking to my ESFP friend last night, when discussing her friends and um the "immoral" things that they do, she spoke much like an ISFJ, expressing deep care and protectiveness over them.
So it like, makes sense to me that they are called shadow functions, but that when paired up it is our "good shadow," which we can act like contrary to a stressed mood. I don't know, I haven't looked too much into like the Animus and Beebe, so I don't know if this is obvious or anything. I feel like it is
Do you tend to act like your "good shadow" if you are in a rather good mood?
