sounds like a very mild seizure, seeing as how you never lost conciousness with yourself... during that 10 minutes, if you wanted to say something, a few sentences varied in structure and vocabulary, could you have done it? thats a sure way to tell if you had a seizure or not.

my math teacher in 9th grade had epilepsy and he had a few seizures during class throughout the year... the tell-tale signs are staring at one thing for a long period of time, and saying the same thing over and over again no matter what the question was.
