I’ve experienced similar, albeit not as dramatic, situations personally and in close loved ones. One night, as a child, I heard what I thought was my parents talking in the living room down the hall. I couldn’t hear exact words, but I assumed it was them. That is until there were more voices, growing in a crescendo and they were definitely inside my head. I couldn’t understand the words and they were laughing and mocking in a “lah lah lala lah” fashion. I quietly whispered a prayer, just under my breath, binding and rebuking them “in the name of Jesus”. As soon as the name of Jesus escaped my lips… silence.

I have no scientific explanation other than a tired child’s brain that was probably overly caffeinated for that time of night. But why the name of Jesus brought relief, I cannot explain.

Later in life, the close loved one experienced what has been diagnosed as manic episodes. I won’t go into the various details of these episodes, but what I can say that mirrors your story is that her symptoms were typically brought on by loud music. More than a few times at church, just as the fervor was building she would dart out from the pews and leave the church. These instances preceded a particularly bad episode where she took the car and drove halfway across the country in immense fear of a “darkness” following her. The stories she’s told me of what she experienced on that drive are harrowing, and I can’t explain them away. She’s okay now, mostly from medication and more secure in her profession and spirituality.

I actually researched the occult and have greatly revised my spiritual beliefs in an attempt to protect her as best I can. One thing that came up in my research was the mention of “dog-faced demons”, which struck a nerve for me because I remember from even earlier in childhood of having dreams where I saw entities such as these and they seemed very interested in me. I shudder to think that I may have been the conduit that brought these demons upon her. So I have focused not so much on protecting her from them, but securing my soul against their intrusion. I could go on more about that, but I won’t, as what seems to have worked for me may not work for all.

That’s the gist of my demon stories. Take it as you will.
