Hi
it sounds like it could be an aura at first - I get quite light headed and then feel like I'm about to faint very odd when I have nocturnal seizures but it's a warning that I may have a seizure.
I used to have absent mals when I was a child - you just stare into space
I'm glad to hear that you are having an EEG as then your doctor will be able to work out what is happening and he'll put you on the right meds
Good luck. My seizures are FINALLY quieting down after puting up with them for 40 years - I had grand mal seizures in the 90's and they were vile !
