This is not a dream, but it is something that God has been putting on my heart:

Most of the world's so-called harmless entertainment is programming people (especially children) and enticing them to embrace ungodly things. The film industry portrays magic as a good and desirable thing, it packages the deception with external beauty, romantic fantasies, enchanting (literally) music, smiles, laughter, indulgence, excitement, and empowerment.

There is more than one meaning to secular movies, music, stories, etc. For example:

The movie Frozen presents a white witch as a beautiful, misuderstood, young woman who saves her world, but not before everything is suddenly frozen.

Peter Pan is a story about a man who refuses to grow up. He visits children's bedrooms at night, tells the children not to tell their parents, and then takes the children to a place filled with other men who refuse to grow up so that they can indulge in their every desire.

There are multiple secular stories about dragons being misunderstood and instead of harming humans, they just want to be loved. When the Bible mentions a dragon, it aways refers to Satan.

Disneyland calls itself the "magic kingdom" and the "happiest place on earth." Virtually every movie they produce (that targets children as their audience) is about portraying magic in a positive light.

Hollywood is about witchcraft. They even showed Harry Potter's wand (supposedly the most powerful available) as being made of wood from a holly tree (holly-wood).

The Bible repeatedly says that magic (etc) is evil. The Bible also says that lying is a sin and that Satan is the father of lies. Hollywood is about fantasy, deception, and lies. The Bible tells us to take every thought captive unto Christ. However fantasy is about being drawn into a world in which you are encouraged not to take every thought captive.

This is a fallen world and we have been lulled to sleep. We need to wake up. Believers, please put on the Armor of God:

10 Finally, be strong in the Lord and in the strength of his might.

11 Put on the whole armor of God, that you may be able to stand against the schemes of the devil.

12 For we do not wrestle against flesh and blood, but against the rulers, against the authorities, against the cosmic powers over this present darkness, against the spiritual forces of evil in the heavenly places.

13 Therefore take up the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand firm.

14 Stand therefore, having fastened on the belt of truth, and having put on the breastplate of righteousness,

15 and, as shoes for your feet, having put on the readiness given by the gospel of peace.

16 In all circumstances take up the shield of faith, with which you can extinguish all the flaming darts of the evil one;

17 and take the helmet of salvation, and the sword of the Spirit, which is the word of God,

18 praying at all times in the Spirit, with all prayer and supplication. To that end, keep alert with all perseverance, making supplication for all the saints... (Ephesians 6: 10-18)
