When I was young, I used to believe that churches were ghosts's houses. My family was not religious, so when we visited a church, I didn't understand why we had to keep quiet. So my Dad told me it was "not to wake the ghosts". Strangely enough, still now, I tend to associate churches and ghosts in my dreams.
