-Selfreference can be distinguished between incomplete and complete. Incomplete selfreference is for instance: you wash your own hands. Complete selfreference is hardly possible: how can you e.g. wash your own self?
-Identity between the observer and the observed is artistic: e.g. to observe the flow of river from a bank; but you might be the flowing river itself! (which is hardly possible!).
