"If we can get you relaxed mentally, with your mind clear of any active thoughts for just ten seconds, you will be asleep. We have three tricks for doing this. First, we want you to fantasize that it is a warm spring day and you are lying in the bottom of a canoe on a very serene lake. You are looking up at a blue sky with lazy, floating clouds. Do not allow any other thought to creep in. Just concentrate on this picture and keep foreign thoughts out, particularly thought with any movement or motion involved. Hold this picture and enjoy it for ten seconds. In the second sleep-producing fantasy, imagine that you are in a big black, velvet hammock and everywhere you look is black. You must also hold this picture for ten seconds. In the third trick is simply to say the words 'don't think...don't think...don't think', etc. Hold this, blanking out other thoughts for at least ten seconds. Now for the next five minutes, using any of these sleep tricks, I want you to try to put yourself to sleep. I will be quiet and you will try to go to sleep. Remember, five minutes only. Let's have complete silence."
