Ghost that Follow
As a general rule, human spirits normally do not follow people from location to location.
Most seem to be drawn to or attached to a building or area. They will remain there regardless of who is living there.
Some of the occupants will know there is a spirit present and others, who are less sensitive, will not.
The location could have been the spirits home, a favorite place or the scene of it's death.
There are a few exceptions to this rule and a few of them are as follows:
Relatives;
Deceased relatives may return to visit the living and they are not bound by location.
Even an earthbound relative who has remained here for reasons that link it to a living relative may follow that person.
Spirits of close friends also fall into this category.
Sensitives or Psychics;
People who are sensitive to spirits may have encounters in different location.
Often these people assume that the first place they lived was haunted and the spirits have followed them to a new home.
What may be happening is that the person is sensitive to spirits and they are now seeing new spirits in this new location.
Many people are unaware that they are sensitive and just assume that these places are haunted.
Spirits are everywhere, and they are drawn to people who are sensitive to them.
Haunted Objects;
Spirits can also be attached to objects. It could be a favorite chair, family heirloom, anything that person valued greatly in life.
Antique dealers often come across items that people claim are haunted.
If the spirit in your home is attached to an object and you take that object with you when you move, the spirit comes along too.
