Residual Haunting Ghost - A residual haunting is a playback of a past event. The apparitions involved are not spirits, they are "recordings" of the event. The event unfolds in front of you and there is no interaction between you and the ghosts. They seem to not notice you and go through the motions of the event that occurred in the past. This event has been imprinted on the area or building and is replayed back later when conditions are right. The ghosts that you see in this type are not earthbound spirits, they are just visual play backs. Often the sounds and images recorded are related to traumatic events which took place at the location and caused some sort of disturbance, which we might call "psychic impression", to happen there. This is the reason why so many battlefields have become famous for their haunting's over the years. An example could be the sightings of Union and Confederate troops marching across the battlefield at Gettysburg. Many people "see" wounded and injured soldiers lying on the ground.
Poltergeist - They are also known as "noisy ghosts" The term "poltergeist" comes from the German poltern, "to knock," and geist, "spirit." There are reports of knocking and tapping noises, sounds with no visible cause, disturbance of stationary objects like household items and furniture, doors slamming, and lights turning on and off. They are known to have caused interference in telephones and electronic equipment. They can also have physical contact with humans and animals, by pinching, slapping, and pushing... sometimes even leaving scratches or bites on ones body. One theory behind this Poltergeist phenomenon is that a person in the household, known as the "human agent" causes the activity. The agent is usually an adolescent girl and normally one that is troubled emotionally. It is believed that she unconsciously manipulates physical objects in the house by psychokinesis (PK), the power to move things by energy generated in the brain.
Intelligent Ghost - This type of haunting is perhaps the most widely accepted kind of ghostly activity. The spirit will usually manifest itself in physical ways like slamming, opening and unlocking doors and windows; strange sounds; voices; cold chills and a strong presence. It may make itself seen and it will most likely look as it did when alive. The witness should be sure however, that the visible spirit seems to interact and is not just an imprinted image. These spirits are known for hiding objects; moving things about; turning things off and on and other nuisances that would be similar to a child seeking attention It is there because of a connection to the site and/or to the people in the location. The spirit seeks to get the attention of the living occupants at or in the location or the spirit may just be seeking company from the residents. This ghost is described as the personality of a person who once lived and who has stayed behind in our world instead of passing over to the other side. This sometimes happens in the case of a murder, traumatic event or some unfinished business that took place in the person's life. At the time of death, the spirit refused to pass over because of these events. The spirits often linger because of the emotions that tie them to the earth, from anger to love. It may not have been that the person did not pass because they couldn't... it may have been because they did not want to. In other cases, there is the chance that the spirit did not yet even realize they were dead. This can occur when the death involved is sudden or unexpected. Remember that these spirits are now made up of the energy that once made up the soul of some living person.. thus an intelligent spirit. The idea of these spirits being still here in our world is actually very sad. In all of our excitement over finding a ghost, we also must keep in mind that many spirits are confused over what has happened to them, sometimes not realizing they are dead. Many of them died suddenly. Because of this, they are drawn back to places where they experienced joy, peace and happiness during their lifetimes. Many of these spirits just felt they had unfinished business on this Earth and have refused to pass over. These ghosts often need help to be convinced that they don't belong here anymore. They need to be shown the right way to go and introduced to the fact that there is now more for them in the next world than in this one. This can be done with the help of a Minister, or spiritualist, or sometimes by prayer alone.
Crisis Apparitions - These spirits appear to loved ones, usually at the moment of their death. They appear to a special loved one that may be miles away, but they wanted to say good -bye to this person.
