I used to have deja vu's all the time, where you think you've experienced the exact same situation before. I think they stopped as a result of my taking Topamax, because other little epileptic things I had going on also stopped. And I would classify a deja vu as a weird brain misfiring equals a mild epileptic thing. And from what I can tell, they don't really do anything about mild epilepsy that is not able to be duplicated at will in a Dr's office. It doesn't really interfere with your life, it just happens once in a while.
