You take a look at the map, and discovered the location for Centaur Fields, and got excited about hearing that. Your mother was aware of your love of horses, so you watch her walk to that area, while you follow her. Centaurs were the most powerful combination of human, and horse combined, and even they know it as well.
When you, and your mother crossed the entrance to such a location, you found dozens of fields of grass, and 1 forest. As you've read about in the books, centaurs gallop along the fields in meadows, basically to get food, and exercise. Just as you, and your mother left for the village, you both got very sleepy, as you crossed through the fields of flowers, and laid down together as you stopped walking. The sounds of the birds, and bright sky didn't keep you awake, because of how relaxing the flowers were, so you both passed out.
