why does he not give the characters names yet?
why is the boy scared to enter his father's childhood house?
on page18 he says, "the right dreams for a man in peril were dreas of peril" then at the bottom of the page there is a contrast because "he could remember everything of her save scent. seated in a theatre with hher besidehim leaning forward listening to the music..." he believes that to dream of his dead wife is wrong because he will never have that again, not in this world and he thinks he needs to forget that life.
a parallel i can think of is near the beggining when he stops at the gas station and collects oil to read a story to his son. then on page 23 they are searching the super market for food and they find the coke and the father gives it to the son. there is a common theme that if theu search long enough the will find a reward. Also the rewards seem to be for the boy. a bedtime story and the coke that the man lets the boy have.
