What are some similes and metaphors in The Reptile Room?

Simile:

“It is like walking up the stairs to your bedroom in the dark, and thinking there is one more stair than there is. Your foot falls down, through the air, and there is a sickly moment of dark surprise as you try to readjust the way you thought of things."

Example of Metaphor:

"Lousy Lane runs through fields that are a sickly gray color, in which a handful of scraggly trees produce apples so sour that one only has to look at them to feel ill."
