duals are people with some functions stronger than at you . you have the same functions but lesser consciouse
when you interact with duals - you pay more attention to your weak functions and this makes them as more consciouse and more active. this makes you wiser in those regions and may add to energy feeling. it's when those weak functions are valued for you. when those are superego - you become wiser there, but also may get depressive, anxiety and exhaustion symptoms. mb as you need additionally to switch to different mode to process nonvalued functions and it's hard for psyche. my experience with conflictors - I feel tired after them in RL and may feel higher doubts without good reasons
