I have this regularly and I am an ENFP.
First off, I'm not 100% sure this is an iNtuitive trait, or rather just a weird psychological phenomenon..
So here's the deal..sometimes I'll be doing something..talking to someone, hearing about something, reading about something, whatever it may be where I am gaining information, a symbol will come to me relating to the topic, which comes without any thinking..I do it unconsciously without even trying to..and when I do realize it, I am absolutely astonished that my brain can pick out a metaphor related to what I may be paying attention to without out me even purposely trying to..another phenomenon that occurs to me sometimes, which I'm sure is an N trait, and can occur when I'm taking in information, and without signaling my brain to do it, I will spontaneously get a verse of lyrics from a song that will instantly come to me related to what I may be thinking about, and not just lyrics about what I'm actually thinking about, but lyrics with metaphors and symbols, which is amazing, and I never intend it to happen, but it does all of the time..
Anyways, I hope you understand what I'm saying, and I want to know if this ever occurs to anyone else..
-I will also be posting this on the NT section, to see what those rationals can tell me (hoping that copying and pasting this thread somewhere else is allowed).
