No idea what it is and i haven't even heard of it until now. If it's a create things game, i'll probably skip it, like i did with Minecraft and other games where u create things. I have no creative skills.
Do you not watch Youtube because you're not creative enough to make videos? Dreams is also a service on which you can search and experience people's creations. You do not need to be creative to enjoy Dreams. If an endless supply of free games, art, music, sculptures, stories, films, shorts etc doesn't interest you then, yes, Dreams isn't for you.
