I know of someone dear whose mother has been sick, gravely sick, for some time now.   Let's call the mother, Mary.  Mary is in her late 80s and her stomach cancer has returned.  In the last several months, she's become weak and has needed care 24/7.  

Today, one of her caregivers mentioned that Mary has been seeing her deceased relatives in her dreams and has told her so.

when I heard this, there was only one thing that crossed my mind.  Mary is close to dying.  My heart sank.
