What is a dream? Every night we enter into the another world, the world of dreams. While we are dreaming, we usually believe that we are awake. Mental worlds of dreams are so realistic that we change them with external world which we share with other people. How is this possible? And why is it happening? What are relations between our day and nightlife? What is origin and function of dreams?
Ponder this; what if our waking life is but a dream and it is when we die that we awake?
