A crossroads in a dream represents a choice you have to make in real life. If you dream you have reached a crossroads, you have reached a time in your life when you must make a decision. You have discovered that you have different options, and you do not have to continue on the same path in life if you do not want to. This could have to do with your education, your career, your relationships, your family or your spiritual development.
The way you behave at the crossroads in your dream will give you an idea of the process that you are using to make your decision.
If you spend a lot of time hesitating at the crossroads and looking back and forth both ways before choosing which way to go, you want to research your options carefully before making a commitment.
On the other hand, if you choose your path quickly, with little or no hesitation, you will probably make a quick, impulsive decision in real life.
If you turn left, it can mean that you will use logic to make your choice, while if you turn right, it can mean that you will rely on your intuition.
If you arrive at a crossroads in your dream, then turn around and go back the way you came, you are not ready for a change or you are looking for other options.
