Residual VS Intelligent Spirits

What is the difference between a residual spirit or an intelligent one? Residual Spirits are the type you most likely will come across most often while out investigating a haunting. Residual Spirits are in fact not ghosts at all but are an imprinted memory. This memory will keep repeating itself, doing the same thing over and over and over. You can not interact with it, it is not aware of your presence and can not be communicated with. The apparitions are simply recordings of a past event in a place where that memory of the event was so strong and full of emotion that the energy has remained in an imprinted recording. An intelligent spirit is an actual ghost that has remained for what ever purpose it may have and can communicate and interact with you. They are made of of energy and they require energy to pull from in order to manifest or do things to attract your attention such as shaking a table or throwing a book down. Since they need to draw from surrounding energy in order to communicate or manifest, it is for this reason you may experience equipment failure such as a battery draining on a fully charged video camera or lights flickering, or that feeling of being under water you may experience. Since they pull energy from the surrounding area it is also for this reason why you will feel a room get really cold or cold spots in a typically warm area. These type of spirits generally have a purpose and although not related to you , may be seeking your help. It is thought that these spirits are the energy of a person who has died unexpectedly or traumatically and will seek out ways to communicate with you and typically mean no harm to anyone.
