What does Silas remember about the time his father took him hunting?

Silas remembers the time his father took him hunting. As Silas walked into the woods holding his Pas's hand, he started to feel strange and his head hurt. Although it was a warm spring day, he felt cold. He told his father they needed to go home as he felt terror sweep through him and mentioned strange sounds. His father told him it was just birds. Silas, however, thought they were voices. When Silas thought he saw something in the trees, he passed out. His father had to carry him out of the woods.
