Child of the Phenomena

Courtney Davis has just lost her boyfriend of two years to a heart condition he was born with. The weird thing is, she remembers having dreams of his tombstone, and he died on the same day as her dream. Trying to forget any of this ever happened, she attempts to return to school, but she begins to see weird things.
Is this just a weird coincidence? Or has God sent someone from her past back to Earth to turn her life around before it's to late to gain entrance into Heaven?
