I’ve got probably the most innocuous ghost story ever, lolll.
When we lived in NYC, my husband had a cat that he’d gotten before we met (ie older cat). He suffered congestive heart failure, and while at the vet, he crashed. They called us up, and asked us if we wanted them to try to save him and we said to let him pass. A minute or two later, our other (younger) cat started playing really enthusiastically with “nothing”, and we comforted ourselves saying that it was the ghost of the older cat.
Over the years, we would feel something like a cat jumping up on the bed, but when we looked, nothing would be there. We’d explain it to ourselves that it must have been the other spouse, a muscle twitch, whatever...just something normal. During this time we moved a few times, and we still felt the jumps. We’d joke that it was the older cat staying with us.
One night at our last house, I was wide awake reading. It was 1am, and the rest of the house was fast asleep. I happened to look up from my book, and as I do, I feel one of the phantom jumps right where I was looking. And as I watch, I see the sheets move by themselves like a cat was settling down! I then started to feel a “purr” against my leg that was exactly like the distinctive purr of the older cat!!!!
A year or two after that, the younger cat eventually passed away. We haven’t felt the phantom jumps since then. I like to think that the older cat waited around until his friend could join him!
