While Vladimir and Pozzo have been talking, Estragon has been sleeping again in his fetal position. Vladimir, feeling lonely, awakens him. Significantly, since Estragon was sleeping in his fetal position, his dreams were happy ones; but even so, Vladimir refuses to listen to them. Vladimir's final speech before the entrance of the Boy Messenger suggests that he feels a deep estrangement from the universe. Something tells him that there should be some reason for him to be here — at this place, at this time, with his friend Estragon while waiting for Godot. Furthermore, he is aware of a misery, a disquietness which he cannot understand. Life seems as though it is astride of a grave," and there is to be a "difficult birth," for the "grave-digger puts on the forceps." Vladimir senses that life is filled with the cries of a suffering humanity, but he has used "a great deadener" (boredom) as a barrier to these cries. Suddenly, in complete despair, he cries out: "I can't go on." But the alternative to his despair is obviously death; therefore, he immediately rejects his despair by asking, "What have I said?" There is left only man's stubborn, useless clinging to a meaningless life.
