Glad to have found this second thread, thanks OP! The first one and now this second make such interesting reading.
Sorry to the poster on the previous thread I spooked with my rural East Devon experience! 😬 I wanted to reply before but got distracted reading the rest of the thread. Wanted to say I have also had similar recurrent dreams to the one you described where there is an unused extended part of the house that was eerie and menacing. Very probably triggered by the experiences at that isolated rural house.
As a household we are Christian but we are a mixed faith wider family with some atheist and agnostic but both those with and without faith saw stuff there and felt oppression, including the woman in the bedroom I mentioned before. On one occasion all of us in the house saw the same thing at the same time, a black shadow in the form of a large cat but bigger, around twice the size with a very long extended tail. In broad daylight, in the corner of the kitchen. We prayed against it and it leapt up onto the counter, out the window and vanished and another cat-like black shadow followed close behind. All of us who were there witnessed it.
We found some strange artefacts in the garden that surrounded the property, there was a very old orchard, quite wild/ overgrown. Strange ceramic charms and objects made from twisted grass or hay near or attached to the trees. We found an old well that had been covered and was completely overgrown, that felt sickening and creepy. There were ribbons tied around some of the trees, possibly wassailing practice. We removed things we felt were not good but sometimes things would reappear a few months later. No idea who would do this as the house was so remote and hidden away down a tiny private access lane.
Nighttime was the worst, did not have a single night of peace there, got to the point I just slept on the floor in the same room as my family as did not want to be alone with the things. One came out of the wall over my bed once, it had the face of a person I knew. I was lying down and it loomed out over me, fixed an awful wide eyed stare then disappeared back into the wall. Horrendous. Wasn’t even the middle of the night just early evening. Could not wait to leave that place. It felt like a spiritual highway, things coming and going constantly, like the walls were made of glass and many unfriendly eyes watching. There was a supposed intersection of ley lines in that location. It felt like we were on ‘their’ turf.
