Nocturnal seizure... what is it?!

Hi all I am new to this forum, and just stumbled across it while trying to search for an explanation of something that happened to me. So my story is... I was on holiays, so was fairly tired after a flight from Australia to New York. I fell asleep around 1:00am and my boyfriend woke up to me at 2:00am having a seizure. Apparently i looked like i was being possessed (charming, i know!). Basically it wasnt jerky movements, but i just lost control of every body movement - i wet the bed, my face muscles had gone all droopy, I couldnt talk except to slur a little bit, and I couldnt sit up. I woke up to the ambulance guys, then within 5 minutes I realised where I was and was starting to be able to speak again and by the time i was in the emergency room, within maybe 20 mins, I was fully functional again. My MRI and CT scans came back totally clear and the neurologist said that it must have been a random seizure (ie he could see no reason for it except possibly exhaustion). My family has a long history of strokes but the doctors said this wasnt a stroke. Does anyone know if this sounds like a type of epilepsy?? If anyone could give me ANY info that would be great. Anyone with a similar story etc. Thank you so much in advance!! alana
