How does Carol Matas use imagery in Daniel's Story?

Imagery:

“I want someone to pinch me so I can feel something, anything. I'm sick of this numbness, of feeling so alone and outside of everything, but I know it's too dangerous to wake up."

"We are each like one of the squares. We choose how our own square will look, we choose the colour, the design, all of that. But when we are put in with the other squares we might be in the middle, at the edge, make the whole look one way or another. ... And it's when we interact with all the other squares that the unexpected can happen. And it can change the way our square is viewed. ... It's a mixture of our choices and God's choices. And it all makes a pattern, but only God can see the big pattern.”
