Sure, it's normal.
It's also normal to believe that at least some of those fantasies can become reality, too, so don't assume that they'll never happen for you. It doesn't sound like you're dreaming about your fame eclipsing Beyonce's or about having more money than Bill Gates; you're dreaming about owning a nice house and running a business. Those are definitely achievable goals. It might take you a while and your path might be circuitous, but you can certainly reach them.
As for the super-cute body, you're here and working on that, so more power to you.
Daydreams are only problematic when they keep you from acting on things that you need to do in your daily life. I can fantasize all I want about writing and selling a novel, but I can't take too much time away from cleaning and cooking and working in the here and now to dream about it. If you're using your daydreams to help define your goals or just put a smile on your face as you drift to sleep, that's totally healthy.
If you're consciously choosing to daydream rather than face a reality you don't much like, well...then it might be time to set about improving that reality. I don't mean big stuff, I mean just little things--clean up, paint your bedroom, some kind of positive change that makes you happy and gives you a sense of accomplishment.
