Based off your responses I'm going to venture a guess at Fe-Ti and then say Ne-Si. (the reminds me of, is what caught my attention for Si)
So from there the mbti types that use those functions would include: INTP, ENTP, ISFJ, ESFJ
INTP-Ti-Ne-Si-Fe - will first look for specifics and analyze data - Dominant introverted Judger. (more serious view of self)
ENTP - Ne-Ti-Fe-Si - first look outward. - Dominant extroverted Perceiver. (so more laid back view of self)
ISFJ -Si-Fe-Ti-Ne - first references past experiences/ subjective sensations. - Dominant introverted Perceiver (more laid back view of self, but will appear less laid back externally)
ESFJ - Fe-Si-Ne-Ti - First looks outward for meaning, relating to others. (Dominant extroverted judger, appears and is more serious. in approach to life)
Also if you are still wondering about Ne try a word association game. Does it energize you once you get going? Do you have a hard time stopping or does this take effort for you to do?
E.g. Soda -> pop -> popcorn -> movies -> inception -> dreams within dreams -> Doctor Who -> blue -> Blue is the Warmest Color -> tumblr...... (took me all of 30 seconds, its second nature for me, that is once I turn it on, but once I do it energizes me. It feels like I'm awake when I use Ne)
What makes you feel most awake (in terms of thinking/ thought processes)?
