Death in itself is nothing; but we fear To be we know not what, we know not where.

Our reading
An editorial interpretation.
The fear is located less in death itself than in the inability to picture what follows. Questions of identity and place remain unanswered, making uncertainty the real source of dread. The lines distinguish an ending from the unknowable state that the living imagine beyond it.
