you are exactly right.....great observation.
I cheated. I have personal experience with demonic activity in one of my children (was being attacked viciously, for good reason, he is going into the priesthood).
The priest and prayer group that prayed over him told me of amazing and frightening things they saw while doing so. 3 of them had visions, one was granted the request to receive the pain my son was suffering. The pain took him off his feet it was so intense. The priest was sick for almost 2 weeks afterward. I was sitting there with him while this was going on. He hit the floor as soon as the priest laid hands on him and the entire group started praying in tongues so loudly and simultaneously that it was actually freaky. He was out for almost 20 minutes and they had to get smelling salts out to revive him. When all was said and done, my son remembered nothing except feeling so at peace and with Jesus. It was amazing. The best part is, we had never met any of those in the prayer group, we had not informed the priest that we were coming to the Eucharistic Adoration/prayer service that this happened at, and none of them knew my son was called to the priesthood at that time.
