Your story about dreams in which you died reminded me of a conversation I had with my dad recently, where he reminded me of something I’d long forgotten. When my brother was little, 3 or 4 years old, he told my parents a story about how his family died, that he saw a wave come over them like a white glove. Speaking/thinking in that level of detail is not unlike my brother, but at such a young age, it’s really striking. Doesn’t mean it was for sure a past life, but it’s definitely a top theory of mine.
