I died.
It wasn't by some special means, it just happened in my sleep.
So how do I know I died?
Well, I'm in a white void and I read enough fantasy books and fan-fictions to know what that means... I getting reincarnated (you can't see cause I'm a soul but I'm dancing)
So it wasn't such a surprise when a god came said I'm dead and that the other person who died was Harry Potter so because there is a prophecy I will take his place, and just before he sent me to Harry's body I said one thing: "What about wishes???" So he gave me wishes but said that for each wish I will lose something equally important- so when I asked for eidetic memory he said all my past life except the Harry Potter books and fan-fiction'swill be forgotten, when I asked for my second wish to be with Tony Stark's IQ he took most of my EQ and when almost afraid,I asked for Lee's work ethics and enthusiasm for work, he took my ability to have YOUTHFUL thoughts (I almost thanked him for that when he said it means I will be with a.d.u.l.t's mind but no experience because he takes my memories) and just when I wanted to cry he snapped his fingers and than I was gone
