Folks are still trying to figure such out. New homes have had ghosts.

No, houses are hunted because their owners aren't taking their meds

A ghost is a spirit ( energy + consciousnas) that for one reason or another has chosen to stay earth bound. Usually for unfulfilled human desires, traumatic deaths, and fear of judgment. The ghost may also be unaware of his or her death, causing it to be a ghost until it realizez that it has moved on. Ghosts are very real, and they are around us all the time. They draw energy from our emotions giving them a temporary charge of energy that they need to exist. They are not all bad, but they all suffer in there own hell that they have created for themselves due to those reasons. They are in two dimensions at once, that is why they can see all. Depending on the person who has dieds spiritual growth, some are more powerful than others. For example there are humans that were priests or socerers befor death, in death, they are as powerful as each other, but in lower= negative, or higher=positive, dominiums. They can and will be manipulated by non human ghosts like angels or demons, from a lower or higher realm than they are at, at the time. And human ghosts tend to remain or haunt the areas that had some strong influence in there last life on earth. This is why some homes or properties are haunted, were, others are not.

Sorry, but NO "haunted" houses exist, anywhere on Earth, EXCEPT in the minds of fiction writers and their gullible readers.
