I've told this before under another username.
My late grandmother was in a care home in her latter years. She was admitted to hospital, I can't remember what for, but possibly a fall. She was due to be discharged and my mother and someone from the care home arrived on the ward at visiting hours to collect my DG.
In the bed opposite was someone else from the care home, lets call her Margaret. My mum commented "Oh look, there's Margaret"
My gran said very matter of factly "yes, she's going to die tonight"
My mum and the carer tried to shush my gran as after all the woman was within earshot and had family visiting her. According to my mum, margaret was sitting up and talking and although looking frail she did not look at death's door.
My gran would not be shushed and kept insisting that Margaret was going to die because she had a 'black cloud' surrounding her. My mum tried to laugh it off and did the 'she's a bit nuts' sign to the family at Margaret's bed. My mum was worried that DG was maybe not ready to return to the care home but anyway she was still discharged and Margaret remained.
The next day, my mum went to the care home to visit my gran who was back in the care home. The carer came running up and said "Margaret died last night!"
The carer and my mum were in total shock and the carer joked that she was going to stay well away from my gran.
But when my mum mentioned it to my gran, my gran just shrugged and said "I told you"
10 or 20 years before my gran would have been freaked out so it's very wierd how she wasn't at all frightend. In fact, its kind of reassuring too.
My mum says that about 40 years ago before I was born, when my DGGran died, DG saw her mother ine the corridor waving goodbye so maybe my DG was a bit woo.
As for me, I often get feelings of deja vu, that I've seen or done something before as things are said or done exactly as I dreamt them word for word or step by step
