similar story for my great aunt. She was in a nursing home while her sister was not. However, her sister had died the day before and my grandma, who had not yet had the opportunity to drive there, phoned the home and asked that they hold the papers so she didn’t find out via obituary.
When my grandma got there to tell her, she already knew. She said her sister had come the night before (a few hours after she had passed) and reassured her that she was ok, and not to worry even though she had passed. What makes this particularly interesting is in “the visit” she was wearing the same clothes she had passed away in the night before. Also, my great aunt was completely lucid when this happened too, she didn’t have dementia or anything similar.
