I had a theory you can predict the future but through patterns of the past or someone's past to predict the next move or they are going to do that same thing again through patterns. Can a person change? 100% can things change? 100% people and things don't change that fast tho. Things tend not to change unless there's a lot of negativity that comes from it. If you get backlash from something you either change the way you do it or just change it all altogether.

@Lox I believe in ripples from the future coming back into the past, and that is what dejavu is and it also has a relation with dreams, visions, and the ability to prophesy
