Location stories

Spoilers ahead:

So I have been playing on and off for a while, and the "Location " stories that pop up seem unrelated and unique. Until I came across the story of the hearts (I think)

It came across as just another weird virus story, but no long after I explored a new location and three stories had combined…

A string of hearts,
A pond with flakey skin
??? (I have no idea if these are correct)

It specifically mentioned in the story that I had seen them previously, but this was the first time they were together. I can’t remember the specifics or what I chose to do previously (probably study them) but I was wondering whether anyone else had experienced similar stories that connect, or whether you have come across the repercussions to your decisions.
