Door Adjar Light On???

Got in my truck(98 f150) to back into the driveway to load some stuff and when i got out the cab light was still on when i shut the door. I got back in the truck a little bit later and since it was dark i notices the cab light stayed on when i shut the door and the "Door Adjar" light was on on the dash. I shut all the doors numerous times and it wont go off. i even disconnected the battery. What the heck is wron with this thing.
