"The boogeyman is real. He might not what you expect him to be. He takes the form of a human, but the bodies never last forever. He isn't always in the closet or under the bed, sometimes he lurks around the school's after hour, or on clear nights he will wander the park. Your parents will fall for his innocent look, but he is not as freindly as you expect. He might want to take you to school and offer you candy, but he is the boogeyman nither less."
Isabella later looks up the boogeyman on her ecto scanner and finds out the boogeyman is a diembodied demon or spirit who wander the earth, as horribel as he is he can't do harm without a human body so every 20 to 30 years he looks for a baby boy with the proper body for himself.
