Have any dualist (closed-individualist) touched on an explanation for the vertiginous question?

To me, the vertiginous question really gets at what makes closed individualism difficult to affirm as a dualist.

While I find the physicalist has an okay answer to this question, given their assumption that nobody has a soul, understanding "consciousness" differently from how I and other seem to mean and understand by it, I don't find that system to be very plausible against my subjectiv experience of the world, placed particularly in both space and time, when the physicalist account of human consciousness shoud be favoring no place and favoring no time either, as some argue. (if I understand correctly)

But I don't want to dismiss closed individualism intuitively without at least hearing out: hav any dualists posited any... metaphors or such that at least explain plausibly that there coud be an answer to the vertiginous question out there, even if we cannot right now pin down what causes the closed-individualist division, in our limited perspectiv of ultimate reality?
