I'm considering the concept that the basic stock for a ghost stew is geomagnetic activity. Toss in some good geology, a tragic history, some extreme emotions, and some human receivers, and you get a hearty mix ideal for ghostly action. When I kept a log in ghost hunting and found that active and promising nights always coincided with activity in the geomagnetic fields of the Earth, I was excited. I wasn’t sure at the time where this finding might take me, but being a person who loves to put together theories, I had to explore. I came across this blurb on New Scientist and it interested me a lot: “The most plausible explanation for the association between geomagnetic activity and depression and suicide is that geomagnetic storms can desynchronise circadian rhythms and melatonin production," says Kelly Posner, a psychiatrist at Columbia University in the US. The pineal gland, which regulates circadian rhythm and melatonin production, is sensitive to magnetic fields. "The ci...
