If you had a dream that a snake is going to bite you, in real life, you expect the situation in which you find yourself helpless in front of their enemies. If you dream you are going to buy something and discover that you do not have or do not have enough money, in reality you will be able to achieve material prosperity, but it will require you to incredible effort. A dream in which you're going on the road, can be taken literally, ie as a prediction of possible trips. In addition, this dream promises change in life.
