Watching horror movies can gives the devil a foothold in your life. We must guard ourselves from opening doorways to the devil all the time because the devil is constantly looking for weak people to attack (1 Peter 5:8). If you open doorway to the devil, there will be a gap in your life that allow the devil to come in and attack you.
The devil can jump on the viewer and possess him through the horror characters in the movies. It can produce bad influence on the viewer. The negative content from the movie can cause the person to become evil and violent.
It can impose all kinds of negative influences in the person including hatred, violence, fear and etc. It instills fear and anxiety in the viewer, which is not from God. As the children of God, we should not fear anything except the Lord. God gives us a spirit of power, love and self-discipline, not a spirit of fear (2 Timothy 1:7). Any other fear comes from the devil. The Holy Spirit, which we receive as a seal of the sonship, gives us peace in our hearts (Romans 8:15).
Some people become fascinated with witchcraft and practice it after watching the movies. Practicing witchcraft is a sin (Galatians 5:19 – 21). We should also abstain ourselves from watching movies that are associated with witchcraft. We must honor God in all that we do (Colossians 3:17). Watching horror movies will not increase your spiritual life so you should not watch them. Watching these movies can lead us away from God. Instead of watching horror movies, we should watch movies that can help us to learn more about God. We should avoid reading horror genre books as well.
The Bible says that we should not have anything to do with the world and demons (Romans 12:2; 1 Corinthians 10:20). The devil use movies with horror content to lead people away from Christ. Even if you don’t believe in the bad things in the horror movies, you should not watch it.
We are not wear clothes or have pictures that show demonic figures. The devil can possess in you through these monstrous figures. We must not wear clothes that show the figure of dragons because Satan is the dragon (Revelation 20:2). Wearing clothes that display the dragon symbol means you are supporting the devil. We are called to live a holy life in Christ. We must be holy for God is holy and cannot tolerate sin (1 Peter 1:16).
