Two Days ago I pulled into the yard (night time.

Two Days ago I pulled into the yard (night time) Turned off the lights and emptied the trunk (shopping) then removed the keys and closed drivers door. I am in the habit of watching tthe interior lights until they go out. To mu surprise they dimmed almost went out then I heard the door opner solenoids click and the interior lights came back on only to keep repeating this over and over. I got out, firmly slammed each door and the trunl lid, no change. I then cycled the interior light switch, started and stopped the engine a few times no change. I then went inside locked and unlocked car with remote, no changed. I removed the batteries both remotes, no change. I then set the alarm, dash light flashed correctly with door lights off for about 15 minutes then dash light stopped but interior lights were still off. At this point I stopped watching but the next morning the battery was to low to start car indicating that it hag started its cycling of interior lights during the night. The next morning I disconnected the battery for 5 hours while charging same as I wanted to see if maybe the computer would reset. No luck, interior lights still dim, door solenoids sound and interior lights come back bright an endless cycle. As of now I have battery disconnected I am at a losss as what to do next?
