Yeah this actually happened to me when my nan passed a few years back. A photo of her literally slid off the shelf about an hour after we got the call, no vibrations, no reason for it to move. Everyone in the room just went quiet.
Not sure if I believe its a ghost thing exactly but it felt like too much of a coincidence to just ignore. I've read a bit about how strong emotional energy can apparently trigger poltergeist activity and grief is about as intense as it gets so maybe theres something to that.
Anyone had it happen more than once or over a longer period after a loss? Curious whether it tends to be a one off thing or if people experience it for weeks after.
