This past Sat I was late to work, due to me not switching my phone from vibrate to ring. I would have been even later if not for the fact that I heard a voice right by my ear whisper my name, at first I thought It was my wife waking me up to tell me she was going to work. But when I turned, and suddenly I may add, no one was there. At that point I realized that my phone was vibrating due to the alarm. I need more storage units .
