Some people believe that films in a dream signify a person’s childhood memories or old memories. These films are often seen as representations of the good times that they had.
In other cases, these films can represent a person’s desires. They give people what they want, but in their dreams instead of in reality.
The cause for dreaming about watching films or movies usually comes from the person’s need to cope with some emotional distress that they are facing in their life. The movie seems to help them escape from reality or pretend for a little while that things are better than they really are.
