Trace My Steps

A young woman has spent almost her entire life in a mental hospital. But while she is in the mental hospital she gets pregnant and has a baby boy. Soon after his birth, she begins to act "normal" and stable again, so she gets released to raise him. But by the boys 18th birthday, his mother is very ill. So he went to go visit her for maybe the last time. But before he left, her last words to him were, "I'm not as crazy as everyone says I am. Trace my steps. Come and find me." The next day, she died. He wasn't there for her death, and she wanted a closed casket funeral. But her words kept playing in her mind, "come and find me." So he dug up her grave. But inside was nothing but her mental hospital bracelet from years ago. So he does what she says and checks himself into the mental hospital, and begins to trace her steps. Is his mother alive? Is this some sort of sick game she's playing? Are there more clues in the hospital walls? Or did the pain of her death cause him to lose his mind...
