The Promised Neverland has always been about the power of family.
Emma's dreams and Conny, Mama and Yugo being the ones to guide Ray to Emma are the manga's way of saying that your loved ones are never really gone.
You definitely should read The Promised Neverland manga, cause its one of my favorite recommended manga.
The reason for that is simply the fact that you probably wish to explore more and see actually what we could've seen.
Try reading this manga, this surely is worth your time.
