A relationship between absence and death?

The spectre of death in theatre and performance has been extensively documented. To what extent do SWG practices take this further? To consider -

People or things that seem to be present but which are not.

The uncanny / Unheimlich

People or things which seem to be alive but which, potentially or definitely, are not (dummies, animatronics etc).

"Acousmatic" - a voice which can be heard but not seen.

Things which move or traces left - by the actions of someone who is not present.

Stories of the first humans to live with photographs of loved ones who had died.


To hear voices

Presence which theoretically should not be present is a very intense form of liveness. 

The spectre of death (conjured into the now) is very 'live'.
