Any other plurals with no connection to anything to do with their plurality?

We personally don't relate but some discord servers and tumblr blogs I follow have mentioned and spoken about the experiences you're listing!

i definitely have this experience. by nature of having DID, i'm very disconnected from myself. i struggle with communication with my parts/alters (that's the kind of language we prefer) and don't really "feel" plural, even in the face of plenty of evidence of my complex dissociation. it is what it is i guess lol.
