They’re talking to Hamlet
Like he can’t see.
They’re stating action that should be obvious
Or at least easily intuited by a pretty smart guy.
What is happening to Hamlet
That they have to narrate the ghost’s actions?
Has he fallen to his knees?
Hidden his face?
Prepared himself to listen by not watching?
Or is he hypnotized by the ghostly face of his father?
Stunned, frozen, eyes so wide he doesn’t appear to see.
