The intersection in dreams is known as the symbolism of the communication or even interaction with those we are surrounded by. If there is some person that goes out of intersection, it shows the feeling you have about certain people in your life who are no longer interested in communicating with you and you are feeling it. If you are in intersection while choosing between something and cannot make up your mind, it means that you are feeling in doubt in your waking life as well, it is difficult to make a final decision. The dream may show that you are in doubt, because you do not have enough of the answers, therefore you feel trapped in your mind.
