They can definitely be hard to understand at first. So basically when they first started, I had one sort of history on who rescued me from a fire, adopted me, etc. And then it's like those never happened and the person who rescued and adopted me is someone else, some specifics on abilities are also changed as if that is how my childhood has always been in them.
It's just weird and I imagine the reason I even can tell that is because I dreamt the first childhood and remember that when I'm awake.
