No, a Christian is owned by God. We recognize the influence, actions, or oppression of demons in the lives of many believers. Jesus saw the need for deliverance from demonization. As 20th century Christians who live in a materialistic culture, we are often hesitant to talk about the need for deliverance from demonic influence. But there is a reality beyond test tubes and our Lord was not embarrassed to speak about it.
Sorcery operates by charms, music, drugs.
Witchcraft operates by spells, curses, hypnosis. Yet most of those whom Jesus delivered from demons were religious Jews, forbidden ever to practice witchcraft or idolatry. Demons are active in less obvious ways than the occult. However, there is no New Testament pattern for holding lengthy conversations with demons. We should not be frightened or surprised by these manifestations.
