You may have to literally look "deeper" than that to the past history of the land itself. Especially if there is any tie to Native Americans. Also, your home may not be the first home to ever be built there. Going back in history you may find that at some point something and someone else had some type of home there. Also look into the area around you. If there are any stories of an evil landowner in the past who lived nearby or an incident of drowning, accidental death, etc. close by. Sometimes these things can travel a bit within the land itself.
