Strange electrical issue
 

This evening my alarm on my 07 G35 went off in my driveway for no apparent reason. I turned it off and went out to check the car and outside it appeared just fine. A short time later it went off again. I got in the car and found the intelligent key warning light was on and the interior lights would not come on. I also could not lock the doors. Fifteen minutes later all lights on the car came on and when I started it the windshield wipers came on, too. So I disconnected the battery and will wait for morning. Any idea what is going on?

Your car's possessed dude. Seek an exorcist ASAP. Demons are not to be messed with.
