Possessed car UNLOCKS ITSELF WHILE DRIVING (210 '97 )

Last week the car started doing something very unnerving. While I was driving the car would UNLOCK ALL THE DOORS and turn on the dome light as if a door were open! I mean the locks would actually raise themselves up into the unlocked position and "click" menacingly as if the doors were about to open. The only way to make the dome light go off was to open and then close the driver's side door. Simply pushing the door lock button had no effect.

Now the problem has gotten worse. Opening and closing the drivers door no longer fixes the problem. Nothing I do will cause the doors to stay locked or the dome light to go off (except switching it to the "always off" position.) Also the floor lights stay on all the time as well -- even when the car is turned off, the key removed, the dome light switch set to always off and the car locked with the remote.

I am afraid that my battery will be run down by the floor lights always being on. More importantly, what could this problem be? A fuse? Help!
