My wife and daughter are far more aware of the subtleties of spiritual occurrences than I ever will be. They are the first to say 'someone's here' and 'it's so and so', or to say ' that's a nice smell, I wonder who that is?'. Regarding this, I sometimes have the acuity of a house brick. Sometimes we all smell a particular scent simultaneously, often, the scent is perceived by only one of us.
I was alone in the living room watching the film Fairy Tale: A True Story, my wife and daughter were in the bedroom looking on the desktop computer. After approximately 10 minutes, an overwhelming scent filled the living room and I shouted 'stop spraying perfume it's making me gag'. The smell lasted for another 10 minutes, and after the film had finished I went upstairs and said 'thanks for spraying perfume it was making me sick'.
They said that they never touched any perfume and they wouldn't waste it by spraying it everywhere. I told them about the smell downstairs and they said that I must have had visitors. As the hairs on the back of my neck stood out they both started laughing. I imagined that they weren't the only ones laughing.
