I can't top most of your stories, but here is a strange incident...

About 30 or so years ago, when we were still living in Colorado, my wife and I and a couple of our children were sitting in the living room when there was a crash from the kitchen. We went out to the kitchen to see a stack of unbroken plates in the middle of the floor. The cabinet door was open, but the plates weren't near it.

Nobody else had occupied the house as we build it ourselves on a parcel of land that had no building on it before and it was at least 1,000 feet from any other homes.

My father had died of a heart attack while working on the house, but it seemed a strange way for him to contact us. There was never another incident since.
