My mom says I used to do that as a baby, although it was just two certain areas of the house, apparently I used to talk with it, play with it, and throw my toys into the area and get my Mom to get them for me, which scared her.
My mam got a priest to bless the house, and it calmed down by like 90%, you could also smudge sticks (sage), Holy/Blessed/Moon Water or a cat in the room can also help sometimes.
Have you looked up the History of your house, for example our old house (where this all happened) was build on a special road called a famine walk. In these roads, people suffering from the famine would walk on these roads because they lead to a harbor, and the ships would bring them to different countries. People would literally just die from starvation and exhaustion on the walk.
Anyway it would help to try cleanse the house in a method preferred by you, look up the history of your house and get a pet cat :) thats just my advice.
