I once had a rather lovely glass bowl shatter for no apparent reason. It was beside my bed, about 5.30 am, I was in bed, awake but a bit drowsy, only myself in the room, I definitely didnt touch it. It did not fall off the bedside table, it just gave this tremendous crack and split into about three pieces.
used this morning so not wet nowhere near the edge last time I realised it was still there (would not have placed it near edge of counter anyway because of DC) not knocked or moved by vibrations/ noise etc
looked up as it toppled gracefully over the edge about three feet from where I was
could swear I saw it shuffle as it wasnt the smash that I noticed, I watched it tumble silently from the top so something must have caught my eye (ie: movement)
any explanations? spooky or otherwise all gratefully received
