You need to read and study to show yourself approved as a workman for God. Don't fall into traps of the occult, false religions and other demonic practices such as certain holidays. Learn to see the forces of evil working in the lives of those people God tells us about in the Bible. There is no unreality in the Bible. Christians should not deal in any spiritual fantasy.
Fantasy is very simply a lie from satan who is the father of lies.
However, we need to learn to walk in divine health as a normal part of our lives. To walk in divine health requires taking care of our bodies and walking blameless before God. Drunkenness and gluttony are the same in the Sight of God. Demonic sex can destroy our bodies and take us to Hell. To get free, you must pray that God will heal you, and you cast out the demons that control your emotions and diseases in your body.
