Dream of person

Im coming home at night, I go to unlock the door of my house..its not locked. I walk in, its dark, I try to turn on a light and the lights aren't working. I run outside and hide behind a tree in the yard. I watch the dark house, suddenly the lights turn on from inside the house. A while later a male person comes out of the house in shadow. I approach him and its a friend. The mood changes from fear to relief.
