Reminds me of this subreddit I came across once called /r/twinflames. As far as I can tell it's like the concept of a "soul mate." I was introduced to it by a user posting about how their life sucks because their "partner" or something (I can't remember what word they used) won't spend time with them. And everyone was like "dude this person wants nothing to do with you leave them alone" and I checked their post history and it was full of this twin flames stuff where they had convinced themselves they had some kind of supernatural connection with some random person who literally did not even want to be friends with them. After a little bit of pushback from people outside that sub they deleted their entire account. Probably made another one and just hang around in the creepy echo chamber after that.

(Oh god one of the top posts right now mentions shifting, there's a connection seriously though this stuff is freaky)
