Funny, "aura" is the exact term I've heard other people use to describe the same phenomenon. Likewise for the precursor feeling before migraines.

Glad the seizures eased up in adulthood (knock on wood). A former coworker of mine was in a similar boat—childhood epilepsy, responded well to meds as a teen, totally fine as an adult. It's borderline miraculous how you can just... grow out of it, sometimes. Brains are strange!
