There is a phenomenon among the dying called a "surge". Apparently, sometimes the brain will suddenly become active and the patient will revive for a brief period before they expire.
Last week, my daughter's mother-in-law died. She was my three grandkid's other grandma. Her health had suddenly declined to the point of no return and she was taken to hospice care where she remained in a semi-responsive state.
All the family members and relatives came to see her and visit over the final days but she seemed only vaguely aware of them. On the last evening of her life, many of the family came to say their farewells. After the older folks had gone, only her five grandchildren remained--all of them in their early twenties.
Their grandma suddenly woke up, threw back the covers and wanted to get out of bed! The kids summoned a nurse who got her up and into a chair. For the next twenty minutes, she regaled them with jokes and wisecracks that had them all convulsed with laughter.
Afterward, she went back to bed and the five cousins left. Their grandma died at 3:00 in the morning.
But, what a marvelous gift she gave them! She left them with those wonderful memories of that final night they had all shared together. They weren't saddled with sad memories of the sick old woman who they had known in her later years. She was the lively, personable grandma they could hold in their hearts as someone who loved them.
Wouldn't it be great if we all had that option?
