“He was afraid of touching his own wrist. He never attempted to sleep on his left side, even in those dismal hours of the night when the insomniac longs for a third side after trying the two he has.”
― Vladimir Nabokov, Pnin

“I felt that what I had been standing on had collapsed and that I had nothing left under my feet. What I had lived on no longer existed, and there was nothing left.

My life came to a standstill. I could breathe, eat, drink, and sleep, and I could not help doing these things; but there was no life, for there were no wishes the fulfillment of which I could consider reasonable. If I desired anything, I knew in advance that whether I satisfied my desire or not, nothing would come of it. Had a fairy come and offered to fulfil my desires I should not have know what to ask. If in moments of intoxication I felt something which, though not a wish, was a habit left by former wishes, in sober moments I knew this to be a delusion and that there was really nothing to wish for. I could not even wish to know the truth, for I guessed of what it consisted. The truth was that life is meaningless. I had as it were lived, lived, and walked, walked, till I had come to a precipice and saw clearly that there was nothing ahead of me but destruction. It was impossible to stop, impossible to go back, and impossible to close my eyes or avoid seeing that there was nothing ahead but suffering and real death--complete annihilation.”
― Leo Tolstoy, A Confession

“Why do you laugh?" I said. "Is it because you hate the sound of laughing?”
― William Faulkner, As I Lay Dying

“My thought is me: that's why I can't stop. I exist because I think… and I can't stop myself from thinking. At this very moment - it's frightful - if I exist, it is because I am horrified at existing. I am the one who pulls myself from the nothingness to which I aspire.”
― Jean-Paul Sartre, Nausea
