The limitations, too, that are common to all sleep were reflected in mine, but in a symbolical manner; I could not in the darkness make out the faces of the friends who were in the room, for we sleep with our eyes shut; I, who could carry on endless arguments with myself while I dreamed, as soon as I tried to speak to these friends felt the words stick in my throat, for we do not speak distinctly in our sleep; I wanted to go to them, and I could not move my limbs, for we do not walk when we are asleep either; and suddenly I was ashamed to be seen by them, for we sleep without our clothes. So, my eyes blinded, my lips sealed, my limbs fettered, my body naked, the figure of sleep which my sleep itself projected had the appearance of those great allegorical figures (in one of which Giotto has portrayed Envy with a serpent in her mouth) of which Swann had given me photographs.
