Silence kills Everything

Rex is a regular high school student. He has average grades and even has normal friends. Nothing special right? Well....... This isn't true when he can see visions of his past life. He doesn't question them because they help him learn from past mistakes, but this changes when he starts to see a girl come into the picture, and for some reason she's crying and yelling for help. The vision is frightening, mainly because after he has it he can sense she's in his school.
