My mum's in a care home and her rather noisy 'neighbour' in the next room passed away recently. The staff swear blind that he was still 'there' for a while. His chair was moving 'on its own', his music playing and so on. They don't usually say it about other residents who have passed on but he was a very strong character and probably left quite an imprint on everyone. Dunno. Mum was in hospital when he died but since she came back, has seen or heard nothing unusual- but she's not really a believer.
Having said that, my partner and I don't live together. We're just round the corner from each other and share a dog, who spends his time at both our homes. The other night, I heard the dog moving about like he normally does when he wants his late walk, which we all do together, to the point where I looked behind me and said 'OK, we're off out soon, mate!' Then I realized he was over at my partner's for the evening, (and, of course) very much still alive! I think my brain was imprinted with the sense that it was getting near walkies time, so maybe 'heard' the familiar noises that remind me. Like I said earlier, the mind is amazing.
