Let's talk about Reincarnation

Have y'all ever thought if reincarnation is a whole ass dream? Like everything is a lie... The reason that they reincarnated is because they're so desperate about some things in their life that they dreamt about it when they died. Which is also the reason why all reincarnation manhwa that I've read is a happy ending. Cause it's a freaking dream. When I think of it like that, I can't help but think "This whole manhwa is a lie"
