My grandmother isn't going to live much longer according to her dr. Her dementia is very advanced.

Yesterday she had crying spells at the rehab center. (Not drugs/alcohol rehab, but the other kind.) Ske kept crying that her mother was dying in a kitchen fire and that she had to go save her before it was too late. Then she was angry and anxious that no one would let her go "save" her mom. And shortly thereafter, she started crying because she believed her mom had "died" in the flames. She felt it was all her fault, too. (Her mom died of old age, so it's not that she was reliving the past.)
