Full Polarity is somewhat complex. Describing through words or pictures really is a disservice (e.g., try describing what salty tastes like without using the word 'salt'). Imagine what it would be like if you had déjà vu all of the time but you could view much further into the future and all of the details were crystal clear. Imagine what it would be like if you could view everything around you with video player-like controls - fast forward, reverse, pause, etc. Imagine if you could do all of this in an instant, on demand.
There are people who generically refer to themselves as Us and Them on a fulltime basis; they do so to protect their anonymity. These are the only people who are capable of truly understanding Full Polarity.
