Why do my doors unlock themselves?

What is your question?

Every now and again it happens while I'm driving. All four locks will rapidly lock and unlock, or sometimes just lock, on their own. That's stressful enough, but it also happens when my car is off. Like when I'm sleeping or at work. I'll go to my car to find all four doors unlocked. I'm sure it's electrical, but further advice would be great. Please and thanks.
