A Trap for the Enemy,or the Enemies Trap?

I have been researching some of the Enemies devices recently...it started with finding out about local legends of the servants of the enemy,A mermaid at a pool a few miles away, a gnomes home under a Hill,I felt it was what the Lord wanted me to do,but thinking back it started with a peculiar hill at the edge of a field, which sometimes I drive past,it’s only very small,maybe30-40 feet high, and 20 feet wide,I don’t know if it’s solid rock, but maybe it must be because why hasn’t the owner flattened it? I can see it’s just a small mound, but it also looks, with ‘spiritual’ eyes like a sort of door way with turrets round,and battlements, very much like a miniature medieval castle..these images super impose themselves at the same time...and I get a warning just before we pass it every time...that it’s coming up, it’s strange because there is no where to stop near it,and the road is angled so I have to drive past quite fast, so are literally just getting one glimpse...just before we pass it I get a warning in my spirit that’s it’s coming up This is a new revelation to me, yes I can and have seen many things ‘in the spirit’but to be shown the hidden houses of the Enemy is a new puzzle to me,!
I know that he and his servants have rights over certain areas,that they have their designated areas,the Bible talks about an Angel being held back by a Prince of that territory...
