My 8 year-old grand-daughter has been experiencing these strange symptoms. He follows her everywhere. He talks to her, and she talks back. He also touches her on the back, scaring her. (None of this is sexual as far as we know.) The only place she can sleep is in her parent's room because her daddy has a gun and he is afraid of her daddy and the gun. She showers with the lights off, because he is always looking at her. What is this condition?
