Did someone die in my house

Why, over the years, most likely someone died in or around every yard in every town.

Most people died at home in the old days. Ask the town hall deed dept when your house was built, and then find out the previous owners, and then go to the library for death announcements in the local paper. Or just assume it's true. Both my parents died at home, one in 2006 and one this year.

If you mean are their bodies there, then start looking under floors.
If you mean spirits, then consult a psychic, for what it's worth,

What's going on that you ask?
