Now thats, wierd. I would never lasted so long, the moment I figured out what was coursing the paranormal happenings that desk would have been out.
I wasnt surprised though to read something had attached it self to an object. Pyschics use pyschometry to devine facts from objects, this is probably just a factet of that to the extreme.
I suspect that the spirit attached itself to the man because he was the one to actually fix the desk, which imparted some of authors own vibration into the object. Why the spirit attached it self to the desk is something we will never know. The author said the desk was handmade perhaps the wood from the desk came from another source, building materials that held the spirit. I think the word processor was the cataylst that may have triggered the spirit: energy attracting energy. Because the author, worked on the desk, and the word processor, the spirit had an easy means to attach himself to the living person. Of course this is all speculation, still an interesting story.
