There's been a lot of posting here about the importance of the site of a haunted house. Essentially, the assumption is that a house becomes haunted because of the history of the land it's built on.
I do wonder if there are other factors involved. Forgive me if I get a bit vague and rambly, but here's an idea of mine:
- what if design and layout are important? Perhaps there are factors in the geometry of a building that allow things to happen, or at least facilitate things happening. I'm thinking about factors like the dimensions of rooms, the relationships of corridors to living spaces, the placement of windows and doorways, etc.
I can't be very specific on all of this because it's not something that's been looked into a lot. But perhaps it should be.
One thing that makes me speculate on ideas like that is that many years ago I tried to learn to play the pipe organ. This got me interested in the design of organs and organ pipes. And when it comes to organ pipes, there's one critical factor that determines whether a pipe will voice at all, and what note it will generate if it does voice, and that is the geometry of the space inside the pipe. Okay, that's a rather stretched analogy, but all the same, maybe there's something in it.
Another factor could be the materials a house is built from. One extreme example: I remember reading Harry Price's book on Borley Rectory, specifically one anecdote. After the fire and the demolition, a local bought some bricks from the Rectory and built a garage. Despite being well designed and soundly constructed, apparently the garage spontaneously collapsed immediately after being build. That's one extreme, but perhaps materials can also contribute to the 'psychic resonance' of a building.
