I used to live in the most haunted village in England.
No sign of any ghosts, but every Halloween the village would be packed with amateur ghost hunters and chav loonies who would run around the graveyard spooking themselves in the process. No self-respecting phantom would appear with all that racket.
There was this other time (at band camp) when I went up to my parents house one night when they were away to feed their pooch and let her out for a run in the garden. I'd spent loads of time at the house on my own cos they'd bought it with a bridging loan and I spent the summer holidays working on the place and the garden/woods whilst they were still in their other house.
Anyway, the pooch hoofed it down the garden as usual and promptly disappeared in the darkness. I took a casual stroll after her and got about 50 yards, when she came running back, which never happened without calling her first. She was well spooked, and I became very aware that the temperature was noticeably colder than it had been nearer the house. The darkness was almost solid and no nocturnal critters could be heard; it felt very oppressive. I've never encountered it before or since. As soon as I got back the house and before I even said anything, the missus said she'd had a very uneasy feeling about the atmosphere at the house that evening. No, we hadn't had a row.
Some of the grounds are ex-MOD land and the site was bombed during the last war, presumably with some casualties. Maybe one of 'em didn't like dags.
