Has anyone heard of a particular phenomenon where elderly living together begin dying in a chainlike reaction close together? 4 months ago I lost a constant in my life. I found her dead in her bed. It was one of the most gruesome and shocking events in my life. One of my daughter's biggest supporters, my grandmother-in-law. I am still grieving and although I have witnessed someone die in front of me before and helped others pass comfortably, this is much harder, as she was a true constant in my life. I loved her. She cared for 2 elder sisters in the home. I did not expect for her other sister to pass a few days ago. I did not find her, but I saw that she was in the fetal position and had fell in her bedroom. This was also unexpected for me, as I have still been checking up on the sister's since I separated from my husband, and she had been doing well last Friday when I dropped my daughter off for time with them! I saw no signs of her death being near. Is there a term for this phenomenon? Everyone keeps telling me that it's common for elderly to start dying around the same time if they are close, is this true? I am worried about the last sister in the home, although she is going to live with the youngest sister, I am afraid she is not far behind. She had been by the other sister's side for close to 80 years, neither married, and they always lived together. I am afraid she will die soon from heartbreak. Is this an established, real phenomenon, for elderly that are intimate or live together to die so close together? Does anyone have any links to research on these matters?
