Mirrors

How does the voyeuristic pleasure of watching, objectivizing the looked-at interact with the desire of the viewer/watcher to identify with what is looked at? The constant need to see the self in as many positions and roles as possible seems to show a need not only to control the objects but the need to occupy their roles, to objectivize the self. Is this need indicative only of Snead's "optical colonialism" or is there also a (possibly fetishistic) need to see the self everywhere, both controlling and controlled, active and passive? Why is there both such a need and such a discomfort with feeling linked to characters on screen?
