What Are Ghosts? A New Theory Incorporating New Thought.

Recently I’ve been watching a show called “Psyhcic Kids: Paranormal Children”, aired on A&E but watched via instant watch Netflix. I’ve noticed that most of the shows are the exact same scenario, some kids can see dead people and some can see what are usually depicted as demonic forces but construed more by the children themselves as negative shadow-like forms that resemble the outline of a person.
My hypothesis: Might these negative forms not be what has historically been represented as “not human” and “demonic forces” be unconscious shadow energies that control our lives manifesting as physical bodies only to the one who is perceiving them? Let me elucidate here. Many of us, in our lives, avoid and deny pain, anger, loneliness, sadness, and even fearfulness through the ego’s protective lens, Fear. In consideration to Eckhart Tolle’s “emotional pain body”, might these children who are sensing dark like negative entities actually be projecting and experiencing their very own emotional pain bodies?
However this may work, whether they may carry them (neg. entity) on into a new life from a previous one, or have the ability to objectively and physically view these emotional pain bodies from this life, it is an interesting concept to think that these negative energy forces that seem to haunt young children, especially female ones, may not be from “the other realm”, but may in fact be produced and perceived by the very same person experiencing them, not as a psychologically defunct brain, but as a real experience of some repressed or suppressed part of themselves. These may be what have generally been referred to as "the shadow people".

What do some of you think?
