The Nature of a Dementor

A Dementor is a Demon Tormentor (in Christian terms, a fallen Angel)

A Dementor is a spiritual being that use to live in the presence of 
the Light, the Source of all Goodness (the Source of the Ancient 
Magic).

The Dementor fell into the world of matter and lost the connection 
to the Light. It misses the Light and continues to seek it.  The 
only place that a Dementor can find any trace of the Light is in the 
goodness of the world.  It is especially tuned into Human Beings 
because each Human Being has a part of the eternal Light within 
them.  Dementors seek Harry most because He has the most Light.  
They seek Harry because Harry is from the Light. (Either He is 
Christ or Christ is within him.)  A Dementor will suck the Light 
from anyone that it can, leaving that person with only darkness.  
But the Light that is sucks from humankind is not the Source, it is 
only the reflection and so it can only satisfy for a short time.  
Before the Dementor fell it was bathed in the Light continually for 
all eternity. If it can suck the soul from the person, so much the 
better because the soul is united to the Light.  In this way the 
Dementor can get the greatest charge of Light.  

RE: Dementors and Ghost
A Dementor is a purely spiritual being that fell into the material 
world. It is the opposite of a Ghost.  A Ghost is a Human Being, one 
born of the material world but with a spiritual nature.  The Ghost 
is trapped on his journey from matter to spiritual.  Hence he is 
somewhat smoky white in color.  A Dementor having been in the 
spiritual world and fallen into matter is black, the absence of 
light.  Both the Ghost and the Dementor are trapped in a place that 
is neither one world nor the other.  Since Wizards and Witches are 
more in touch with the spiritual world they can see the Dementors 
and Ghost whereas a Muggle cannot. 

If the books go according to what I think is the plan, Harry will 
free the Ghost and the Dementors from their prison.  Both Ghost and 
Dementors have free will and they will have a choice when the time 
comes to go on to/back to the Light or stay in the Darkness.
