question: Last two nights my child woke up with quivering bottom lip, mouth full of saliva,unable to speak and in a trancelike state for several minutes until he becomes aware of his surroundings. He tries to speak but cannot and after several moments when he can it is garbled sounding. His lip quivering is not controllable and he spits out large amounts of saliva. Both times these episodes lasted 20 mins until normalcy returns. This May or may not be related but he often makes a clicking noise while he is sleeping.
