My grandmother is 93 and has a very good memory, she is very alert and can remember things very easily about her child hood. I visited her this morning and she said she hasnt slept for 3 days. She told me at 11pm every night she hears the voice of my late grandfather who died 5 yrs ago calling her. She gets up and waits for him to talk again, she waits all night.
Im not sure if I should inform the rest of my family as I dont want her going without sleep for much longer.
Is this a common thing?
I don't want to be alarming, but she is 93 years old. She's lived a long life. It's not beyond some understanding (in my experience with end-of-life situations) that she feels her husband "calling her." She may be preparing herself to leave this body behind.
However, I do think the rest of the family should be told the story because people do sometimes decide on some level that they've had enough, so to speak, and then their family finds that they "suddenly" died. Many long-term elderly couples die within days or weeks of their spouse. Their reason for living is gone.
It's possible that your grandmother will continue to live for some time. If she's not physical or mental pain, that's good. But do prepare yourself and your family for the possibility that her life will soon be over.
Take care of yourself. You sound like a wonderful grandson.
Get her to the doctor to rule out a UTI, which can cause hallucinations, or any other acute illness. Have the doctor review her medication for anything that might be causing this.
To help with her emotional distress, ask her if she would like to write a letter to her husband, to let him know what has happened to her, and how much she misses him. Of course she can't send it, but she might enjoy communicating with him.
