Ghosts versus Shadow People

Is there a difference between ghosts and shadow people? I think in most cases there is; in 1 there isn't.

First off - ghosts come in a variety of 'flavors'.

1. Residual hauntings - occur when an emotional scene of event is embedded in the surroundings. The ghosts seen in a residual haunting do not interact with the living; they just repeat some action from their existence...over and over again. They are oblivious to the living.

2. Intelligent hauntings - occur when the ghost interacts with the living. The ghosts want to communicate and will make noise and lower room temperature to manifest itself.

3. Demonic hauntings - are self-explanatory.

Of these 3 types of ghost hauntings, I believe the intelligent hauntings most resemble the instances of shadow people - but this video begs that belief.



Just what are shadow people? Are they demons? Lost souls in limbo? Or aliens that watch our lives and scare us in the dark?
