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. Thus, a strain of gentle music, or the rippling of water in a silent place, or the odour of a flower, or 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; which some brief memory of a happier existence, long gone by, would seem to have awakened; which no voluntary exertion of the mind can ever recall. ~ Oliver Twist
