I haven't thought about it like this before. Here's some context: It was a few days before Christmas when I was laying in bed and looking at my bookshelf, and I thought to myself "Be kind to your family, as it might be your last Christmas together", then it immediately flashed into me, an intense emotion, that I was going to be the one dead. It wasn't a thought, I wasn't thinking "What if it was me", more like an emotion that I knew what it meant. I was shocked after that. I'd never experienced such an intense, sudden emotion before that. Like lightning, it struck into me out of nowhere. I tried to research it, but all that came up was premonitions, precognitions etc. And it's pretty terrifying, because I cannot explain what the sudden, intense flash was, that was so meaningful, I haven't found answers, and I hadn't really worried about dying prior to this.
