My dad died very suddenly 8 years ago.. literally dropped dead of a heart attack at home. It was very sudden and very shocking.
The night he passed I stayed with my mum as he had died in their bathroom, and I obviously wanted to be there for her as she was in total shutdown/no visible emotion shock.
I went to bed eventually.. she said she wouldn't be sleeping so not to worry if I heard her moving about.
Three things happened that night.
Firstly a lightbulb in my brothers old room suddenly exploded. Really loud bang and shattered glass everywhere.. shorted out all the lights so I was scrabbling about in the fuse box trying to get the power back on. I have never experienced a lightbulb blow as violently as that.
Secondly my OH who was back at our flat across the other side of London with our v young DC was aware of a constant banging coming from one of our wardrobes. He investigated several times and found nothing. He is in no way a fantasist/woo etc. He said whilst odd he didn't feel freaked at all. It stopped about halfway through the night never to be heard again.
Thirdly my sister and her exDH Who lived in another city had a knock on their door late the same night from the Police saying a 999 call had been received from their home phone. My sister was still in shock re my dad, and obviously had not rung them. Police asked who else was in the house, which at the time were their 2 DC.. one 5 and one 3, both of whom had been in bed for hours and hours. Police left eventually, my sister was freaked.
Now I don't know if any of it had any significance, possibly just an evening of strange events following a traumatic incident earlier in the day ( think body bag/coroner's, CID officers on the scene etc).
I do wonder though if my dad hadn't been ready to go. There were signs he had tried to grab objects on his way down.. broken soap dish, towel on the floor. Maybe he needed to let us know.. I dunno. I have had grief counselling in the past, and I'm not sure if any of it makes me feel better or worse.
