An evil spirit medium casts a spell, gains full control of a person's mind and the person becomes a slave of the medium. The victim begins to think and behave exactly how the spirit medium wants him to, losing the ability to think and act for himself. Those who are under this attack starts doing things against their will and they become like a puppet in the hands of a puppeteer.
Lord Jesus break the spell and sets the person's mind free from the slavery to the spirit medium. He then heals, restores and empowers the mind of the person.
Since the attack is enforced, the person can also be delivered without his consent.
It was for freedom that Christ set us free; therefore keep standing firm and do not be subject again to a yoke of slavery. Galatians 5:1
You were bought with a price; do not become slaves of men. I Corinthians 7:23
For you have not received a spirit of slavery leading to fear again, but you have received a spirit of adoption as sons by which we cry out, “Abba! Father!” Romans 8:15
I have come across victims whose minds are enslaved by spirit mediums and a few people have been set free from this attack in my ministry.
Even though not a very common attack, this attack is being used to force others to act in a way that suits the attacker's will.
