“When asleep we go back to the old ways of looking at things and of feeling about them, to impulses and activities which long ago dominated us, in a way which seems impossible in the waking hours, when the later self is in the ascendant. In this way the rhythmic change from wakefulness to sleep effects a recurrent reinstatement of our ‘dead selves,’ an overlapping of the successive personalities, the series of whose doings and transformations constitutes our history”

-James Sully
