At a Sunday morning service 20 years ago, my wife, myself, and about 20 other brothers were praying.
This meeting was exclusive for prayer, as the main church service was held on Sunday night.
There was a guy, a newcomer, who was gay and was trying to get rid of this sin.

He was sitting in a chair and as the prayer got more intense, he started to slide to the floor. When we realized, he was lying on the floor, agonizing in pain, and started to crawl towards the door. They moved exactly like a snake, it seemed that it had no bones, it was much easier to get up and out, but he was no longer in control.
The brothers intensified their prayers and the inner animal screamed and screamed as we reprimanded him in the Name of Jesus.
Had meny experiences during these yeas with real exorcisms.
