Hmm, I see you want details. Let's see here.
First, you must determine what the dream is. Let's say you dream of owning a snowmobile.
Next, you find a weakness. Let's say you want a snowmobile so badly, you're willing to settle for a used one, even if you have to take it to a repair shop after you buy it.
Then, you hook your dreamer. In this instance, someone tells you that they have a snowmobile that's perfect for you. Your hopes are built up. Your dream of owning a snowmobile is about to come true. You spend a lot of money getting ready. You take snowmobiling classes, buy a trailer and a snowmobile cover, liberate space for it in your garage, hire a mechanic to take a look at the snowmobile after you buy it, buy plane tickets if necessary. Things like that.
Then, just when your dreamer is ready to have their dream fulfilled, you snatch the rug right out from under them. In this instance, you are told that (for whatever reason) you can't have the snowmobile after all. Maybe you discover that the person you were going to buy from never had a snowmobile to begin with. Maybe they were just exploiting your dream for laughs. Who knows? Suddenly, however, you find yourself unable to trust the next person who offers to sell you a snowmobile. Perhaps you even start to believe that owning a snowmobile isn't worth the hassle.
That's how you steal a dream.
Now imagine that happening to someone who wants to adopt a child.
And, before you begin to squawk at me, remember you DID ask and I'm sure many other dreamers out there will agree that I haven't missed much in my step-by-step instructions.
