note that unified experience is not necessary for consciousness to evolve
We know from concentrarion camps literature that under high stress , helplessness and information overload,
experience can be fragmentized-
into very short intervals seperating one chain of events from another like short "shots" in filming
Eichmann to Kant: I refute thee thus
Kant: But I define this as a pathology of consciousness
The philosopher: But there is a conscious experience in this state
Let's ask Eichman few more questions about his experience before being hanged when everything is sensed unreal
So that at least we can say that consiousness is malleable and assuming various states, of which unification or even homogeneity is not one

"Is not one"
should be
"are not shared properties (or common denominator) "
