One of the most curious aspects of ghost hunting to me are the so called 'residual hauntings', also known as 'recordings'. The reason these are so intriguing to me is because they seem to make the least amount of sense. In an intelligent haunting, the haunting seems to be caused by some sort of non-physical entity, whether it be a ghost, demon, or something else. Although these situations can be mysterious, if you already believe or know these beings exist, then the mystery becomes more a question of why they are there, instead of if they are there.
But a residual haunting doesn't appear to be intelligent. It appears to just be a recording of a past event. So if it isn't a ghost or intelligent non-physical entity, then what causes it and why? And what causes one event to be recorded but not another?
What got me thinking about it is a friend of mine who has Post Traumatic Stress Disorder (PTSD) since returning from Iraq. He admitted recently that he still hears 'radio chatter'. This is different from 'hearing voices' in the traditional sense in that the voice (or voices) don't appear to be intelligent, or 'living'. He described it as being 'residual'. In other words, he just hears 'recordings' of radio chatter.
The effects of PTSD don't appear until after returning from war because the adrenaline rush is no longer there. I don't know exactly what causes it or where it is 'recorded', but there does seem to be a residual effect on the mind.
So I wonder if the earth experiences something similar? Are residual hauntings the result of the earth experiencing a strong emotional event in a particular location? Can the earth remember this event after the emotion - the adrenaline rush - is gone?
And if it is a recording, then what is the event recorded on? A popular theory suggests certain types of rocks (such as limestone) can record events. Another possibility is atmospheric conditions. But how would events be recorded on rocks? We can record information on magnetic surfaces with computers, but these are specifically designed for recording information. The computer serves as a conduit. But what is the conduit for residual hauntings? If we assume for a moment that certain types of rock can record events, then what is the conduit that makes it happen? Are phonograph records, casette tapes, CDs. DVDs, hard drives, and flash drives a naturally occurring phenomenon that we have overlooked? Or are we going in the wrong direction altogether with the rock hypothesis?
If events can be recorded on certain types of rocks, then another question we could ask is can those events be erased? If we quarry the area, would the residual haunting go away? What if a shopping mall is built in an area where a ghost train had been seen before? Would building the shopping mall erase the 'recording' of the ghost train?
What if these 'recordings' aren't recordings at all? What if they are glimpses of past events as they occur? What if there is some sort of 'wormhole' that is attached to a specific location at a specific point of time that occasionally opens and allows people to view a past event as it occurs?
But if we can see recordings of past events, could people in the future potentially see recordings of people living now? Or if the wormhole theory is more accurate, could people from the future be watching an event occurring right now without the people involved even being aware that they are being watched from the future?
There are many questions regarding this subject. The questions could have multiple theoretical answers, but I think it would be difficult to prove any of those answers. But it is an intriguing mystery.
