There are two haunting types to know:
- Voluntary hauntings
- Involuntary hauntings
Voluntary hauntings mean the spirit made a decision to stick around. This could be an attachment to a person, like a relative, or a special place, like their home. In these cases, some people try to convince the ghost to move on to the after world.
Involuntary hauntings usually involve some kind of trauma or an environmental factor that traps the spirit. Some parapsychologists believe rocks can record the person’s energy and leave a signature behind. This is thought to be a major influence on residual hauntings. In the case of trauma, someone’s passing may have been so quick and stressful, the spirit doesn’t know the body has died.
