Dreaming of actors is very common today and in most cases it does not have any meaning as per dream interpretation. It can have a meaning of desire fulfillment only if you see and actor that you had long forgotten.
Dreaming of actors you were once a fan and then forgot about them means you will soon achieve fame and success. It also means honor.
Dream of actors whom you are not a fan means you will have to go to unknown places or accommodate people with whom you are not so friendly.
Today it is very common to see dreams of actor as we see them in real life or on television and are their followers. Dreaming of actors after witnessing a movie or scene or news does not have any value as it is just a mere extension of what happened during the daytime. The dream to have a meaning it should happen naturally not under influence of daytime activity.
