If you've had trouble with TMJ in the past, then even with your specific symptoms seeming unusual, one would assume it was related. On the other hand, there is a rarer medical problem called Trigeminal Neuralgia that can cause an experience much like the one you described.

Wow. I've had a lot of different types of pain in my jaw but never a shooting one.
That must have been a horrible way to wake up.
