One of the themes of Edward Hirsch's "My Grandmother's Bed" is the experience of childhood. The adult speaker describes his memory of staying at his grandmother's house as a child. He reflects on the wonder he felt at sleeping on a fold-out bed with wheels, which was so different from his own bed. He recalls his grandmother's snoring, which to an adult might have been annoyance but to a child is a source of adventure; the rhythmic movements cause him to dream of sailing on the sea. He wakes up the next morning to the smell of his grandmother's cooking, which he associates with a feeling of comfort and safety. The poem illustrates that childhood is a time of rich sensory stimuli and exploration.
