Many people have their dreams at night. We have also got some experiences of dreams. In our dreams sometimes we see ghosts, wild animals, great buildings, juggles, dead people, murder, friends, etc. In my opinion, we see these persons, animals, things because of our unsatisfied desires. We have experienced that what we desire in a daytime, occurs in our dream at night. So the desire of getting something might be the cause of the recurring dream. In the same way, sometimes we see the same dream day by day. We have experienced the fact that we fail in our exam in the dream if we are waiting for the exam result. So far might be the cause of the dream.
