Ghost Hunting during a Thunderstorm

[Gary]

I was watching Ghost Hunters this week and they mentioned a theory of performing an investigation during a thunderstorm could possibly allow a spirit to manifest itself easier due to the increased energy in the air.  So, this does sound like it makes sense, does anyone have any experience or knowledge about it?

I've looked into it a little myself but I wanted to see what everyone else has to say about it!

Well, for a long while now there's been this assumption that an ion generator optimizes environmental conditions for paranormal activity in the same manner as storms, because it stimulates electromagnetism, the putative medium for "spirits".  It's a common misconception, though, that thunderstorms are responsible for this.  In fact, it's the lightning, not the thunder, that ionizes the air and stimulates electromagnetism.  I don't really know if there have been any longitudinal studies to confirm one way or the other that ionizing the environment actually works.  I suppose it's possible that the EMFs involved are responsible for the illusion of paranormal activity for those who are sensitive to them, but I don't actually know if ionizing works.  I fear it might be as dodgy as White Noise Generators.   Does anyone else know?
