There are Degrees of Demonic Activity

To deny the existence and influence of demons would be to ignore or mythologize the many gospel accounts of Christ's ministry of delivering people from demonic bondage. These were more than psychological delusions or hallucinations. From the first-century church in the book of Acts to the present day there have been clear evidences of demonic oppression and control. 

The Bible does not actually use the term "demon possession."

The usual expression is that he or she "has" a demon or an unclean spirit. The Greek word, daimonizomenoi simply means, "to be demonized." This term allows for different degrees of demonization ranging from influence to oppression to control.

there is Demonic Influence

For though we live in the world, we do not wage war as the world does.
 The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds.
 We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ.
 And we will be ready to punish every act of disobedience, once your obedience is complete. 2 Corinthians 10:3-6
 But I am afraid that just as Eve was deceived by the serpent's cunning, your minds may somehow be led astray from your sincere and pure devotion to Christ. 2 Corinthians 11:3
 Do not deprive each other except by mutual consent and for a time, so that you may devote yourselves to prayer. Then come together again so that Satan will not tempt you because of your lack of self-control. 1 Corinthians 7:5
 You know that when you were pagans, somehow or other you were influenced and led astray to mute idols.
 Therefore I tell you that no one who is speaking by the Spirit of God says, "Jesus be cursed," and no one can say, "Jesus is Lord," except by the Holy Spirit. 1 Corinthians 12:2-3
 So I counsel younger widows to marry, to have children, to manage their homes and to give the enemy no opportunity for slander.
 Some have in fact already turned away to follow Satan. 1 Timothy 5:14-15

there is Demonic Oppression

Then Peter said, "Ananias, how is it that Satan has so filled your heart that you have lied to the Holy Spirit and have kept for yourself some of the money you received for the land? Acts 5:3
 "In your anger do not sin": Do not let the sun go down while you are still angry,
 and do not give the devil a foothold. Ephesians 4:26-27

and there is Demonic Control (domination in the mind)

the Spirit of truth. The world cannot accept him, because it neither sees him nor knows him. But you know him, for he lives with you and will be in you. John 14:17
 You, however, are controlled not by the sinful nature but by the Spirit, if the Spirit of God lives in you. And if anyone does not have the Spirit of Christ, he does not belong to Christ. Romans 8:9
 The churches in the province of Asia send you greetings. Aquila and Priscilla greet you warmly in the Lord, and so does the church that meets at their house.
 All the brothers here send you greetings. Greet one another with a holy kiss. 1 Corinthians 16:19-20
