Noises I hear when I'm home alone

Full disclosure: I'm a 31 year old adult.
  1. Things rustling outside
  2. Someone with mechanical gardening equipment... is it the neighbours or is it in my yard?
  3. Someone standing just outside the shower...
  4. Someone in the garage?
  5. Was that a noise coming from the closet???
  6. A sound and a shadow as I walk by the bedroom....
