Strange Voice

I don't know if I am a person that strange things just happen to or if I attract strange things. What I do know is that odd things just happen. Like for example a more recent event. I was in my house by myself when out of nowhere I hear small soft voice asking where's Andy? As you would imagine this made me stop and pause. Especially because my father's name is Andrew. So I wonder is this ghost in my house or my mind playing tricks. If it was a ghost it could be my grandmother since she was the previous occupant of my home. She also died in this house. But that does not make sense because she always called my dad Andrej. (Polish for Andrew) The interesting part of this experience was the voice seemed to have tone of concern of where my father was. Its like it know something was wrong because of my father absence from my house.
