Bit of a weird one this. May be a coincidence, my grandmother who was more like a mother to me died in 2006. I have her ashes. I’m in my 5th house since then and each house I’ve lived in the bathroom tap at some point or other have turned in themselves. Usually sink but last house was bath tap/shower. They’d be nothing for ages then over a few weeks it would happen regularly again. Been in current home a few months and kitchen tap started to come on by itself. I wasn’t in the room at the time and was outside and heard the water coming down the drain as the wash owl had filled up. No one else was downstairs at the time. About 30 mins ago my young daughter told me that whilst she was on the toilet this evening the bathroom sink tap turned itself on. I can’t explain it unless I keep buying houses with dodgy plumbing
