I bought a house that was built in 1938 and the previous owners had lived there for about 50 years. For a long time I felt like there was another person in the house, but living alone I knew this wasn't possible. This "feeling" continued for several months. One day when I felt the "presence of this person" I just sit on my couch and said out loud "I will take care of your house." I never had that feeling again.
