Intelligent hauntings are a completely different type of haunting from residual. Whereas a residual haunting is a type of energy that has no consciousness, the intelligent haunting does have consciousness. These spirits have been accounted to interact with the living all throughout history. There are many possibilities why an intelligent spirit may elect to stay on our physical plane. Below are some common explanations:
1. Many spirits that are considered to be intelligent simply may not realize that their life has ended and they are trying to continue living as if they would if they were still alive.
2. There are some who may elect to remain on the physical plane in an effort to ensure the safety of particular loved ones.
3. There may be a strong connection to a particular place, item, or person on the physical plane that results in the spirit remaining in our world.
4. Many of the spirits may feel as if it is their obligation to send a specific message to a loved one.
5. In some instances, it may simply be that the spirit is frightened to move on from life to death, and that they need time to get used to the idea that they are no longer living.
