Maybe like a neverending lucid dream, only things are consistent and make sense. And maybe I don't fully realize I'm in complete control, but things still happen exactly how I want them to subconsciously or something. I say I wouldn't want to be fully in control, because that would mean if I were to imagine other people, I'd know instantly that they weren't "real", and I think that would be lonely eventually.
I guess something like omnipotence in my own little universe would be cool, too. Like, I could lay out entire lifetimes for myself in different situations and worlds and whatnot, and then remove my knowledge of omnipotence and just live out those lives to the fullest, completely happy.
