As she stooped over him, her tears fell upon his forehead.The boy stirred, and smiled in his sleep, as though these marks of pity and compassion had awakened some pleasant dream of a love and affection he had never known; as a strain of gentle music, or the rippling of water in a silent place, or the odour of a flower, or even the mention of a familiar word, will sometimes call up sudden dim remembrances of scenes that never were, in this life; which vanish like a breath; and which some brief memory of a happier existence, long gone by, would seem to have awakened, for no voluntary exertion of the mind can ever recall them.
Charles Dickens, Oliver Twist
