Re: It it a seizure
Mine didn't start out when I was driving. I was usually at home and sometimes at school (teacher). The first time that I had one while I was driving was the night I ran into my husband's car. Before I always thought if it should happen while driving, I would have time to react and pull over. That was not the case that night. I remember the déjà vue experience as I always do. The complex partial seizure that happens after that, I have never remembered. The night I ran into my husband. He got out of the car at a traffic light and I slightly remember that part of it. I kept driving to church with my 3 children. I made it to church. I remember my son saying 'mom you're freaking me out, what's wrong with you'. I pulled into the parking lot and my husband and son were looking at the vehicles, and I remember my son saying 'dad she doesn't remember any of it'. I ignored them and kept right on walking into the building. It was about half way through Bible study that I started to realized that 'something' had happened. Most of the time I don't even realize the complex seizure even happened.
One happened in the hallway at school while I was being medicated for seizures. Another teacher followed me to my room and told me what I did in the hall. When she told me that, I clearly remembered the simple partial seizure. It felt like the room was very large but I was very small. My medication went up and the 6 month driving suspension started all over again.
Sometimes it's like déjà vue, sometimes it's like weird distortions around me. They are all different, but those I always remember. I feel like (just my uneducated opinion) the 'snapping out of it' experience you describe could be a complex partial...or at least that's what mine felt like even though I didn't know or understand what was happening to me. The most serious...in my opinion are the ones when I was driving. Not just because of the obvious reasons...I could have killed someone, but when those happened I was in a real fog and it took awhile to fully 'snap' out of it. That's the only 2 times I felt that way.
I was 47 when I was first diagnosed with epilepsy, but I had been having the déjà vue experiences for a long time before that. I had the tunnel vision feeling too...mine started to change as time went on. One time I remember an episode where I was crafting on a snow day home from school. I remember sitting at my dining room table just kind of staring, and then I remember the feeling as if I had made myself snap out of it. There are so many different auras and feelings that you can get, and mine changed over time.
Please see a dr asap. I didn't consider my auras as a problem until the night I hit my husband. If that had been someone else I had hit, and the police was called...I would have probably gone to jail because I did not respond in a normal fashion to my husband, and I know I wouldn't have with a stranger or a police officer. It's too serious with lifelong ramifications to either you or another innocent person to not have it checked out and treated.
The day after my last day of driving, my 9 year old twin girls were telling me what happened. They told me of a house that I had pulled into the driveway and hit their basketball goal...totally don't remember that at all. I drove the route I had taken the night before because we were on our way to my daughter's basketball game. They showed me the driveway, and oddly enough it was the house of a friend of mine. On my way home after that, there were 2 women walking their babies on the side of the road just before I got to my house. I realized that if I had a seizure then, I would have killed those people. I turned my keys over to my husband, and I haven't driven since. That was in September.
Please see a neuro as soon as you can. My sincerest best wishes to you.
