THE METAPHOR OF BIRCHES SWINGING IS IMAGINATION. WHAT IS THE REALITY?

When the narrator looks at the birch trees in the forest, he imagines that the arching bends in their branches are the result of a boy “swinging” on them. He realizes that the bends are actually caused by ice storms - the weight of the ice on the branches forces them to bend toward the ground - but he prefers his idea of the boy swinging on the branches, climbing up the tree trunks and swinging from side to side, from earth up to heaven.
