Ghosts or The Invisible Beings

Majority of Ghost and Other stories take place at night.  You often hear of Orbs appearing on camera shots, the Dark Shadow Beings flitting tombstone to tombstone, and of course the Knockers, Rappers, and Flying objects are often encountered in the dead of night, but why is that?

I have been mulling over this for some time now and I believe my hypothesis is fairly logical and legitimate.   Sunlight is energy, a very large amount of energy even as mild as it is felt on Earth.  At night there is that much less energy mucking up the ethereal energies of the Ghosts and Other beings so we can see them much easier.  It is like staring at a flashlight that is pointed out from the sun towards you.  You can't see the light of the flashlight because the Sun's light is much brighter, but take away the Sun and the flashlight's light is now much clearer. 

A popular way for detecting Ghosts is by feeling for "cold spots".  Energy creates heat, so in the "cold spots" there is less energy, but where does it go?  Since there is less ambient energy at night it makes sense that "cold spots" and drained batteries are a result of paranormal beings using that energy to manifest themselves in the more visible or audible manner. 

Have you ever wondered why some people never encounter paranormal activity?  It could be because they don't believe and so prevent manifestations around them.  Just the tiniest bit of belief and you may end up giving enough energy to a lurking being to manifest in some way.
