I'm talking about a long-term state Louai. Yes, short-term you can have lots of happiness with no sadness. But for an entire life, there must be sadness to balance it out. Otherwise the happiness will fade and it will no longer become happy. Things tend to be balanced, so if there is absolutely no sadness or bad things, the good things will equalize as well. After many years of living in your own beautiful world of lucid dreaming, the things that were once so amazing and happy would no longer have any significance. You would eventually be left to walk around in a world where nothing matters. It wouldn't necessarily be boring, as that is a "bad" thing, but it would just be a drab world that has nothing for you. It would be like an eternal limbo. I know that is not what I want.
