The experience started in my garage. I had been playing drums for one hour. I heard a voice which said in my ear, "Your getting pretty good". I then saw a reflected figure in a mirror out of the corner of my eye. The figure was not in any place in the room except for in the reflection. For further notes the voice was female, my great grand mother passed away two weeks before.
