What metaphors are used in Nightmares & Dreamscapes by Stephen King?

Example of Metaphor:

“Better to be a mouse behind the wainscoting, nibbling at the wires. Better to be a spider, high up under the eaves, spinning its web."

“Nightmares are the mirrors that reflect our darkest selves.” This powerful statement underscores the notion that when we are plagued by terrifying dreams, we are confronted with the depths of our own fears, insecurities, and inner demons."
