I've been watching many testimonies on YouTube, and I've noticed that sometimes Christians testify about having experienced paranormal activity, presumably attributed to the action of demonic entities. The following are some very illustrative examples: A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q. I personally have not experienced anything like this, but it appears that many do. Have you ever had to deal with paranormal activity? What was it like? What would you recommend to someone who is going through this and wants to end the oppression once and for all?
