To dream or not to dream ...

Suddenly I realized that I don't really have dreams.... Not that I don't want anything, it looks that I just cannot dream. You know like some boy who was dreaming to fly, all his life. And he became an austronaut. Ok, when I was a girl my dream was to work at a factory on a hard pressing machene, work hard all day and be tired by the end and feel good because of that.... And be the best.... Socialist realism. After that I didn't dream, I kind of worked, studied, did what I had to do.
And now I have something I like to do, I enjoy to do, I want to do , I look forward to do....And I am almost embarrassed to admit it, as if I am doing something wrong, something not important, something shameful to admit. Is it because I never learned to dream and that's why feel this way? Do we have to be taught how to dream or it comes naturally?Does ability to dream influence our lives, helps?  Do we have to teach our kids to dream?  I never taught mine. Can they dream? I should ask them and may be talk to them about it. Now I dream to buy Nikon d7000, go shooting, take that wow picture, be noticed... wow, it is difficult to write about it...
