Precognition is the ability to see the future. Precognitive skills may reveal themselves in many ways. Some people who use their precognitive skills may use nighttime dreams. More avenues may be available to you. These avenues may include daydreams, hunches, visions, clairaudient experiences (you know the voice inside your head) and "gut feelings." Everyone is different. It is up to you to decide which method is best for you.
