How do you know if there's a spirit in your house?

the way to find out if you have a spirit in your house or your friends house is when you feel a breeze while you are just by yourself or so you think;if you hear things and you go to check and no ones there; doors,Windows,chairs etc. move by themselves;you here people talking or argueing and when you check no one's there;when alone you here footsteps;your TV will turn on and show you something that happened on the news about someone dieing;you find something in the news paper about how the spirit died; and if you take a picture with no flash and see a bright light in the corner of the picture or a different person in the picture.
