Hello brother. I believe its demonic attachment. I don't think your possessed. Christian people have power in Jesus name to order Satan and evil spirits away. Understand, unclesn Spirit can attachment to those who don't have holy Spirit.
Im not judging anyone. Matthew chapter 12.
Now when the unclesn Spirit has gone out of man, it roams through waterless places in search of rest, but it doesn't. Then it says,ci will return to my house from which it came.
Inoculation of God's word is important. Not studying, not repentance, resisting holy Spirit, or involved in traditions of men and false doctrine. I know of Catholic girl in 1997, I cut off contact. I converted to Christianity in 1999. In 2004. There was message on my answering machine. It was 5 minutes long, derogatory and hate. Halfway through her voice changed to masculine voice. She admitted she is possessed by demon and evil.
I would never attempt a exorcism on her. Why ??? She surrendered to Satan. She willingly gave her mind to him. Exorcism won't work. She doesn't have Faith, and hates Jesus. Any Christian is putting themselves in dangerous situations if they attempt it.
It will work, if the individual wants the Demon out. And must have faith.
On that answering machine. Satan spoke. Told me, he tired to destroy me 6 years earlier. He said to me, he will try to destroy me in the future. Demonic possession is absolutely real !!!! . I personally experienced it. I dated her period of time,1997. I fell in love. She used it against me to try to destroy me. I've never dated again. We understand this.
In Acts chapter 19. Seven sons of sceva, priest, tried exorcism on demon possessed man. They messed up. The Demon possessed almost killed them.
Repent, and order Satan and evil spirits away from you in Jesus name. Study Bible. Get that inoculation. Keep away from traditions of men. Peace.
