You just did a great job of putting into words something I've been experiencing for decades. Missing someone and not knowing who she is or even where she is, other than sometimes to be encountered in my dreams. I know her every time I contemplate her, but, as far as I know, I have never actually met her. More accurately, it's more than one person, but the other one is akin to a shapeshifter and takes on significant characteristics of women I have actually known and lost who possess significant characteristics that would make them excellent sister wives.
This sense has, for me, been associated with my gravitating toward wanting a plural family as far back as to before I was an adult.
Thank you for articulating this,
@Asforme&myhouse.
