When I was in school, I'd dream of riding a sports bike. When I was in college, I'd dream of riding a sports car. I am now employed, and I don't dream like that anymore, for I know better than that now.
Also, why would I want to dream living someone's life? Won't I be disrespecting my own when I do that?
I'm not picking on you, just putting my thoughts across. You're free to dream what ever you'd like, and that's fine with me.
