They are people caught between two worlds. Each has experienced a terrible tragedy. They must now live in broken earthly bodies as well as exist in the spiritual world. These people have chosen to remain in their broken earthly body to help their loved ones. They are individuals who know the time spent in their broken earthly body will serve a life-altering purpose for those they love. Only when this purpose is served can they be free to go completely into the spiritual world. This is what they all agreed to when given a choice after their tragedy.
