This happened to me about three years ago, week after my dad passed. A mug he used every morning slid clean off the kitchen counter while I was just standing there. No vibration, no one walking past, nothing. I'd heard about this sort of thing but always assumed it was grief messing with perception or whatever.
What gets me is it only happened that once, and it felt almost deliberate if that makes sense? Like it wanted to be noticed.
Has anyone looked into whether there's a pattern - like does it tend to happen more in the first few days or weeks after? And does it matter how close you were to the person? I'm wondering if theres something to the emotional connection side of it or if its completely random. Would be good to hear if others have had similar and what you made of it at the time.
