It is not the dream that gets programmed, its the mind. Your dreams base themselves off of what you currently know, and if your programming your real-life self to do reality checks, it is reflected in your dreams because of it.

If you want to dream about something so badly, you either have to 1) Have a lucid dream and switch it around so that you get what you wished for, 2) Become obsessed with what you want in real life so that it may eventually carry over into your dreams, or 3) Get lucky.
