Clarice Lispector said this quote

I see myself abandoned, solitary, thrown into a cell without dimensions, where light and shadows are silent phantoms. Within my inner self I find the silence I am seeking. But it leaves me so bereft of any memory of any human being and of me myself, that I transform this impression into the certainty of physical solitude. Were I to cry out — I can no longer see things clearly — my voice would receive the same indifferent echo from the walls of the earth.
