I've never discussed this with anyone other than my parents, but; I predicted the death of two of my grandparents, 5 years apart and while I was 150 miles away. Both times I had a sudden and horrendous feeling that I can only describe as a "disturbance in the force" and I just knew. I was right both times, they were dead within 24 hours. I phoned ahead to my parents both times and told them what I was feeling and why I was coming home in a rush.
To this day I have no idea how or why I knew. I'm an atheist, I do not believe in the supernatural. In fact, I'm a scientist and this kind of shit does not sit right with me at all. I have lost A LOT of sleep chewing this over in my mind and it still make me question a lot of things.
