There are many classification for epilepsy and forms of seizures. But, after reading and further investigating this particular type of epilepsy, I realised I may actually suffer from it...
Petit Mal Seizure (recently known as Absence Seizure)
Occurs mainly in young people
Brief loss of consciousness (10 to 20 seconds)
Blank expression
Spacing out
Eyes may roll up
Person is not aware of 'absence'
May be triggered by boredom
Yeeup...happens to me everytime I sit through a lecture.
