What metaphors are used in The Man in the High Castle by Philip K. Dick?

Metaphor:

"Things are seldom what they seem - skim milk masquerades as cream"

"She had always told Frank that he was ugly. Large pores. Big nose. Her own skin was finely knit, unusually so. Did he fall dead without me? A fink is a finch, a form of bird. And they say birds die."

"We're blind moles. Creeping through the soil, feeling with our snoots. We know nothing. I perceived this...now I don't know where to go."
