Anthony was 5 years old when he started hearing and seeing what he says were spirits. The intensity of so many different voices would keep Anthony awake at night, and eventually he would spend sleepless nights in his parents' bedroom. When asked why spirits contact him, 10-year-old Anthony is very matter of fact. "They knew I can understand them. And if they tried to talk to someone else they wouldn't understand."
