I too am epileptic & just today I happen to have run across a forum on epilepsy.com that may be of some help to you. Please check out the below link, I hope it helps you!
I understand that the link was removed...oops, I didn't realize I'm not allowed to post links to other forums. I'd still like to suggest you visit epilepsy.com & search 'aura' in the forums, there was info & discussion that sounded like what you describe; you are not alone.
I just checked, the thread was called "How exactly do aura's feel"
I've been an epileptic for over 30 years. What you describe was what my first aura's were like. Many times, you can have an aura and never have a seizure. Now, I can have a seizure and not have an aura to warn me.
Luckily I still havn't had any more seizures but as I was saying I still get these weird feelings the doctors say that theres no trace of epilepsy anymore but I get these annoying feelings, I sought of still get the same feelings, but I get others kinda as well if anyone else knows what im talking about please leave comments
