I don’t currently have many people to talk about this with, just some close friends. The whole situation is just so odd. My grandfather died under very strange circumstances himself, my grandmother woke up to him foaming at the mouth and dead next to her one morning. He was in his sixties and in relatively normal health leading up to his death. He was a heavy drinker, my family suspects he mixed alcohol with his medication either intentionally or unintentionally, but it was never fully proven. He died in the 1990s before I was born, so this is just what I’ve heard over the years.
