When he was little, my father used to play in a wooded area near his house. One day, he was playing when he suddenly felt a presence behind him. He looked up, did not see the man's face (all he knew was that it was a man) because he was so tall and then bolted as fast as he possibly could.
When he arrived home, he wrapped around his grandmother's leg and stayed in that position for the entire night and perhaps longer, I can't remember. When he explained to his grandma about what he had seen, she told him that perhaps he was a the "protector of children" warning him that something awful was about to him if he had ventured deeper into the woods.
I just finished watching a documentary on the "Slender Man" and realized that my god, what my dad saw fit the description perfectly. The trauma inflicted on him also matched the symptoms of meeting this man. Has anyone met this guy? He likes staying close to wooded areas.
