In 1967 my folks bought a house in a new housing addition in our hometown. This housing addition was built over land that once was the site of a sanitarium. After we lived in the house for a few months, especially on weekends, my mom would tell me to turn the tv off or lower the volume - after not getting any response she would come to my room and I'm sound asleep! it wasn't me who had turned on the tv! And then on Sunday afternoons there would be chamber music in the living room of our house - and then every now and then you'd feel a breeze as though someone was walking past you - so I guess you could say I'm a believer!
