Sometimes, your real desire to win a prize, can trigger a dream of winning a scratch card prize. If the prize is small and offered in large numbers, the chances of actually winning one are numerous. If the prize is big and only one or very few are offered as prizes, the chances of winning are slim.
If you dream of winning a scratch card prize, and you have entered in one, this dream is probably a product of your wishful thinking triggering your desired dream.
