Dreaming of a movie means you are living your life passively, and never taking true action to succeed. You are not considered original and ring true to the term copycat by emulating your favorite actors rather than being yourself. At the end, you are only limiting yourself by holding on to movies that have long played out its welcome.
The movie as an element in a dream is typically symbolic of one’s desires, suppressed memories, and suppressed emotions. The movie can represent what we would like to see happen in life but don’t have the courage to pursue for fear of failure or disapproval.
If you dreamed about watching the same movie you have already watched, this could signify that there is something repetitive going on in your life that you would like to change.
