I think it's because people are more paranoid. There is no ultimate "time" that paranormal activity marks on their calendars to appear. Except maybe dead time that happens at 3AM. Everything is still and if I'm not mistaken the energy levels give the spirits more leeway to come forth. Paranormal activity can happen anytime. It'd be fascinating if Halloween really did stir up more but, Ghost hunters live tonight doesn't seem to stirring up a lot of activity. Ugh, and that guy from ECW as the guest is annoying me considerably.
