If you unlock the door by turning the key in the drivers side lock and hold the key hard over for a few seconds, the windows will roll down. There might be a glitch or bad connection in the lock/switch mechanism that is causing it to happen on its own.
If that isn't it, then try wrapping the car with foil. You are too close to the Puget Sound Naval Ship Yard if you know what I mean. (just kidding)
Now that I think about it, try driving some distance away from the Bremerton area and see if it still happens. You never know what the Navy is testing lately. There might be a chance that some sort of RF interferance is tricking the remote alarm.
