Trees are hanging from the sky, their roots are snakes, or sometimes rivers, their leaves are fish. Are those roots entwined in clouds or stars? Our hero's mother warns him about nightmares, but he doesn't mind because he loves these trees. Even so, it's a good thing his bed is close to the ground because he is a little bit scared of heights and, when his dream knocks him out of bed, he doesn't have far to fall.
