"But my dreaming self refuses to be consoled. It continues to wander, aimless, homeless, alone. It cannot be convinced of its safety by any evidence drawn from my waking life. I know this because I continue to have the same dream, over and over." (Moral Disorder, Margaret Atwood)
Perhaps it's never enough because my dreaming self remains unconvinced. There'll never be enough proof. Never enough bolt holes.
And yes, I do have the same dreams over and over.
