a few ideas come to mind. anxiety? stage fright? low blood sugar? even if you've never experienced these before they can come on suddenly and without warning. did these symptoms occur when you were doing something in front of the class? if so my guess would be you experienced an episode of anxiety. if you weren't performing in front of the class then perhaps you had a bout of low blood sugar (hypoglycemia). even though you say you ate breakfast the quality of the breakfast can influence your glucose levels. for example if you ate only pancakes and syrup you certainly could experience a dip in your sugars. if you ate some protein along with some whole grains then it would be less likely you experienced a dip in blood sugar. if you are otherwise healthy and this has never happened before there's probably no need to have it checked out. we all experience occasional bouts of panic or hypoglycemia. if it happens again or begins happening frequently then you should make an appointment to see a health care provider for an evaluation. good for you for maintaining your hydration. it's very important to overall good health!
