True to my wife's dream my aunt passed today. We were there when it happened. I was talking to her when I noticed my wife look oddly over to the door and then immediately at my aunt. She died a few seconds after this. My wife told me that she'd glanced over at the door and seen my (deceased 2 years ago) dad standing there. He then seemed to move quickly out of the doorway. When she looked over at my aunt, she'd passed away.
Sorry for your loss, and I hope what I am about to say doesn't sound disrespectful.
She was 80 and had pneumonia. With respect, I've never even met your aunt, but even a godless heathen like me could hazard a guess that she wasn't going to last long.
