It must be understood as a dynamical system, fluid, chaotic. Experience is what it does. Experience is what I do. It is not as though I am a rider on some wave of experience, to whom its qualities are transmitted. I am that wave, experiencing.
Subjectivity is essentially the first person experience of the activity of the conscious brain.
In other words, it is the experience of being inside these processes of the physiological brain as described within the language of phenomenlogy. What it is that is out there is not what it is that is in our Brains. Our consciousness of the world must be dynamic, in order to keep up with the world, and causal, in order to get what we need from the world, otherwise there is no point in having it. If there is no point in having consciousness then it most likely wouldn't have evolved. We are looking at a multiply bifurcating neural processing system forming a processing hierarchy with feedforward and feedback pathways enabling feature extraction, quality recognition, object reconstruction, recognition and naming, cross referencing and global binding enabled by the reverberant structure of output being routed back into input layers and cross-fed into other modality pathways.
