Everybody has a dream at night but most people forget them. It's okay to have no dreams at all, a lot of people say they don't just maybe they don't have a good memory...lol
Sometimes it's good not to have dreams, the night goes quicker!
"Having concluded that dreams were the arena in which the unconscious mind could express itself, and that they were primarily concocted to represent the fulfillment of a wish..." From the book '50 Psychology Classics'
Have you been having much sleep, lately? When I had little sleep I never dreamt but now I've started to sleep more and have dreams.
