This is what is referred to as an intelligent spirit. It is a spirit who has for one reason or another not “crossed over” and has remained here on earth.

These spirits may cause some trouble, but not half as much as a spirit who has never lived as a human.Apparitions that have never held human form are sometimes referred to as poltergeists. These are the rarest and most dangerous forms of spirit. They are also sometimes thought of as demons.

A team of ghost hunters will arrive on the scene, each with their own “ghost hunting tool belt.” This is essential to a successful hunt. It includes some rather obvious things, as well as modern, technical equipment.The first few items one will find are very simple. They include: a flashlight (preferably shockproof as well as waterproof), a watch (if 4possible, with an illuminated face), a thermometer (to record cold spots), ...
