The term ghost is widely used to refer to any paranormal activity that occurs in the home, but it is really a misnomer. Ghosts or the spirits of those who have passed on may cause a paranormal disturbance in your home, but they are not the only cause of a haunting. To determine the type of haunting, an understanding of different types of entities is necessary.
- Residual Ghosts-Residual ghosts are probably the most common type of haunting. It is believed that when a traumatic or emotionally charged event occurs in the lives of the living that it can be imprinted on the environment. Certain geological features like the presence of water, limestone and other stone features seem to hold images of past events. The residual ghost is seen performing the same tasks, walking the same path or singing the same song at regular intervals. The characteristic person searching for a lost love or walking passively through the area they inhabited when alive is almost certainly a residual ghost. They repeat the same pattern whether you are present or not. You can't interact with a residual ghost because it is not aware of your presence. In fact the residual ghost is not really present at all and is simply an image of a past event.
- Intelligent Spirits-Intelligent spirits, sometimes referred to as earthbound spirits, can interact with you. No one knows for sure why the spirit of some people remain on earth, but paranormal investigators and researchers believed that the person has unfinished business to complete or is unaware that he has died. In some cases it appears the spirit lingers simply because it chooses not to pass on to the next realm. Intelligent ghost may attempt to communicate with you by making sounds or moving objects. It may appear as an apparition that resembles the human form or appear as a mist. This ghost may react to your activities or respond to requests. Direct questioning during an EVP session may elicit direct responses.
