No, I don't believe in ghosts or afterlifes, once you're dead that's it, the end.
People just attach things to grief, they see a feather falling while they think of thir dead dad and decide it's something to do with them. But what about all the other feathers they see?
People say a bird (often Robins) will fly around them, but birds do that all the time.
A light flickers, which lights do all the time.
My stepdad died last week, we never had a good relationship but he'd been asking about me the day before he died. I didn't find out until Saturday morning, but on Friday afternoon (around the time he died) my electrics blew, my cat was acting really odd and my dishwasher flooded my kitchen.
Now was that my stepdad? Or was it the fact the switches tripped due to getting wet somewhere and the cat was bothered about the water and me stressing about it all?
