To attend or watch a movie or television screening in your dream suggests that you are watching life pass you by.
Perhaps you are living vicariously through the actions of others.
Consider also how the movie parallels to situations in your waking life. Alternatively, the dream suggests that you need to take a step back and look at some waking relationship more objectively.
To dream that you are undergoing a medical screening suggests that you need to take a closer look at your actions and your motives.
More directly, the dream may be telling you that it is time to go in for your doctor check up.
