I had a “haunting” experience that lasted over a month, either a fit of temporary insanity or a bonafide Demonic assault. I heard shouts from downstairs when upstairs and heard shouts from upstairs when downstairs, saw objects move on their own, woke up feeling someone caressing my hair or pulling the blanket off of me, and finally climaxed by getting grabbed while in bed by an unseen, growling/hissing foe.
A prayer sent it off and stopped all the other phenomena in the house.
