My theory on ghost and the paranormal

After years of watching all the paranormal shows on tv and my own experiences I have a new idea on the paranormal and how it works . First I believe there is a difference between demons and ghost, this covers just ghosts. I was watching ghost adventures and they were investigating a poet that lived in this wierd castle house . He said he would return as mist. Unlike the popular theories that ghost are interdeminsional or electromagnetic this takes a different perspective . I think he may have been on to something .Ghosts are people who have passed , obviously. But humans made up of over half water. When we pass can the conscious that we have transmit into moisture? I believe so . Let's take a look at classic ghost stories. What is the setting of most of them? It's usually on a dark and stormy night... These stories are for fun but they originated from somewhere . Usually the basements of buildings tend to see a good amount of activity, basement also hold on a lot of moisture. People always investigate and hunt for ghost at night. Nighttime usually sees higher moisture levels with the cooler temperatures. Our brain works off of electric signals throughout the nervous system , electricity could be transmitted through places with high moisture , and since it is everywhere it would allow these faint electric currents to travel with ease. Another thought is in older houses there is wood , old wood . This wood had asorbed moisture over a span of decades making older buildings a battery or memory bank of the paranormal . It would explain dispite all the equipment people have used to catch the paranormal any good results besides an orb here maybe mist there. If proven true then dehumidifiers could be their downfall and if anyone ever made a back pack dehumidifier we could start ghost busters! Just a thought . On a similar note , wtf is up with these paranormal investigators and their "interviews" with ghost . These were people not phantom lab monkies. If they had a normal conversation with them or something themed to their era they would probably get better results over " come talk into the thing on my hand " or " make a knocking sound again"  . No respect or consideration at all!
