As a paranormalist, it is inevitable that at some point you will be asked by a client or home owner how to remove a ghost from a home or business. As a paranormalist the real question should be, is it your job to remove a ghost versus educate the client about haunting's. By definition a paranormalist is any person that actively seeks out a personal paranormal experience. The definition usually applies to apparitional experiences (ghosts) but has gained recent use in other fields such as Cryptozoology, and ufology. It should be noted that paranormalists are all inclusive of any interested party seeking to experience the paranormal first hand. Ghost Hunters (generic term) and paranormal investigators, are paranormalists, however such groups usually operate and investigate with their own style, beliefs, and doctrines. Due to the broad spectrum of beliefs and practices from one paranormal group to another, it is currently impossible to agree on what a ghost is, or if a ghost can be removed.
Most parnormalists will agree that apparitional experiences seem to fall into more than one category, that is, assuming ghosts exist. Haunting's are believed to range from benign to dangerous. The most common types of haunting's and ghosts include residual and intelligent. In addition, there are poltergeists, demons, and shadow people phenomena which may fall within the accepted range of apparitional experiences.
To be clear to the reader, as a paranormalist the desire is to experience the paranormal first hand; as a caring and empathetic human being the desire is to help those afflicted by the perceived affects of apparitionaal experiences, if possible. When speaking about ghosts, the best all encompassing definition given for an 'apparitional experience' is a anomalous quasi-perceptional experience. Keep in mind there is no scientific proof ghosts exist, this is merely a definition of a theoretical idea.
Back to the original question proposed, can a ghost be removed from a location? The best answer is no, however there are many parnormalists that honestly believe they can cleanse -remove spirits from a location and even a person. Cleansing's and rituals to remove ghosts, or dark energy have been used almost as long as the belief in ghosts. As with most aspects of the paranormal there's a broad spectrum of ideas on ways to cleanse or remove spirits. Results of cleansing's are also highly inconsistent, no one specific method, has been proven to work and be 100% effective.
The act or ritual of spiritually cleansing a location, item, or person may have a psychosomatic effect on the living, giving the false sense that a spirit has been vanquished or moved on. The psychosomatic effect is difficult to ignore as it may in fact make a homeowner feel at peace, when in reality nothing spiritually has changed. This revelation may lead the paranormalist wondering, did a ghost really exist at all? and did they in fact, only fuel the overactive imagination of a client?
Charlatan paranormalist, are a growing issue within the paranormal community. Charlatans, are not paranormal investigators at all, they are less than scrupulous and con clients into paying money to investigate, spiritually communicate and cleanse haunted locations. Any individual or group of paranormalist who seek to charge clients for services should be avoided.
