have you heard about the term 'Synpath' / 'Otherhearted' / 'heart-type' ? its an otherkin thing,(im not sure if it applies to real people though), it seems really similar to your /identi thing, albeit with a bit more mirroring? (sorry if this message seems bad or cringe or out of bad faith or anything, this is a genuine suggestion and i hope you have a good day 👍)
