The Layout of a House in Minnesota

My best friend passed away a few weeks ago. Before she was in a coma I was the last person to talk to her. We were talking over Facebook call and chat until she was placed in a car and drove away from her house and the wifi cut out. The day she passed I woke up to a message that said, why aren't you answering your phone? And it was a voice mail that was her very muffled and low crying. She died three hours after I received that message and she never woke up from her coma. It still haunts me and just don't know how to get rid of it.
