It's not a dualism at all. What the OP is proposing is similar to Spinoza (probably the most hardcore monist to ever exist), where mind is a fundamental property of the universe (in fact, there's only one mind) and each individual person is a 'mode' of it.
It's effectively akin to talking about mass. Despite the fact that mass is observable as a distinct phenomenon in any object, it's obviously not accurate to say that you "produce mass" or that it's "your mass" in some private, ontologically separated way, it just appears that way, by definition if we look at particular manifestations of it.
