The possible existence of a spirit or ghost world.

"Carol Ann!, don't go into the light"

-- Scene from Poltergeist 1982

Talking about ghosts and a possible ghost world is a very difficult, strange and confusing subject, and it does not help that there is no 'hard evidence' for the existence of spirits, ghosts or any other pure non-physical entities. However, undoubtedly, we all have heard many stories about ghosts, spirits and other unexplainable mysterious ghost-related events, possibly including extraordinary psychokinetic phenomenon.

How would we describe these non-physical entities? What would be the characteristics of such a pure spiritual being? Let's look at a few of the names that they have been known under:

Non-physical entities we know of from stories:

Stories about ghosts and spirits have been heard and recorded through the centuries. It is a fact that every culture has its own collection of stories and histories about the existence and interaction with non-physical entities. Although ghosts are sometimes 'seen', more often their presence is noticed by something else than any of the 5 senses. In spite of all the witness evidence and extraordinary psychokinetic phenomenon observed, there is still no conclusive proof for the existence of ghosts, spirits or any other non-physical entity.

Many well known stories not only inform us about the existence of non-physical entities, but as well about the communication, interaction and involvement of these beings with our world. Many Religion for instance believe in a some sort of direct communication between humanity, gods and angels.

The popular belief that humans can directly communicate with non-physical entities exist over thousands of years. Every culture and civilization knows of ways to communicate or interact with their spirit world, often using terms like praying, meditation or séance.

Further to the possible existence of pure non-physical entities, there is the belief that each human being has a spirit, often referred to as the soul. Although two physical objects cannot exist in the same space-time, a non-physical entity (a soul) and a physical entity (a body) could possibly share the same spot.

Although there is no proof that humans indeed may have a soul, religions treat it as an important part of being alive. Often indicating that life on earth is only a short stop on the road of existence, and that the journey of the soul continues in the after life. The soul is believed to be immortal, time has no effect on it.

One of the core ideas behind the detached non physical entities (like gods) and attached non-physical entities (like souls) is that they have conscience, a will and intelligence.

A first step to proof the existence of possible non-physical entities might be to develop a way (perhaps a device) that is able to replicate what mediums are believed to do. If we could prove the existence of a soul and its capability to detach it self from its physical host than this might change dramatically our view of our selves and the world that surrounds us.
