OK... my turn.
When the MS snuck up on me, my neuro did a EEG (?)... (the test with all the wires stuck to your head... like William Hurt in Altered States).

Anyway, turns out I had a mild form of epilepsy. As soon as he started quizzing me on it, I remembered times when someone had to 'snap' me out of it. And feeling like I was suddenly hypnotized or stoned.

But that's just me...
