Weird experience with the afterlife

I was in the afterlife (I know I was because I felt the vibe), and there was a little guy who was telling me things about life and death. He was like an angel. And he said "you know, when a person dies they come to this realm and stay here for 3 days, and that's why when you die you feel the memory of your past life". This is not something a normal person would say, because he's an angel, he's supposed to know that kind of thing.
