Why was my 2016 MacBook Pro keyboard illuminated when I woke up? MBP wasn't plugged into anything and isn't scheduled to wake up, the laptop was flipped in the open position all night. When I glanced at it at ~8am the keyboard was illuminated. I didn't touch it.

Did the camera sense movement which caused the laptop to wake up?
haven't had this issue again. must have just been a bug.
