I do not wish to use the subject's real name, for her protection. I will call her Jane. This is the true story of an exorcism I performed on Jane. We were the only two people in the house at the time.
I was woken up at three in the morning by a whisper. Through a clenched jaw Jane wispered again - 'help me' was what she said. She had been trying to choke out the words for an hour. I looked at her, trying to figure out what was wrong. Her expression changed from fear to anger, then back to fear. I could feel the evil manifesting, and I knew it was a demonic presence. I immediately began praying and ordering the demon away in the name of Jesus. Jane's reaction was shocking. She bacame furious, angry, violent all at once. She was screeching sometimes words I could not understand, sometimes just sounds. She clawed at me with her nails, tried to kick and bite me. I was forced to hold her down forcefully to protect both of us. Suddenly, the Holy Spirit came upon me, and I spoke with a more commanding voice and tone than I thought I was capable of. I knew what to say and how to say it - the knowledge was simply in my head. I ordered the demon out of Jane, in the Name of The Living God - Father Son and Holy Spirit. It was suddenly quiet in the room. I noticed how dark it was, the light had gone out. Jane's eyes were tired and full of fear. She grabbed me in a huge bear-hug, tears streaming down her face saying over and over again "Is it gone? Is it over?" I saw the clock - it now read 3:45 am, almost an hour from when the ordeal began. Jane told me later that she did not see me when the Holy Spirit came over me, she saw an angel, and a shining light blinding her. She remembers very little of the experience to this day, but that is the detail that stands out the most in her mind. I remember something similar, a dark shadow with eyes over her.
Believe me when I say that the movie "The Exorcism of Emily Rose" got it right. Nearly every detail was absolutely correct.
