I have pseudo seizures as well but they went away for 5 years and then came back in the last few weeks. Nothing triggered it. I have also had fainting when I was a teenager. I am 28 now. Sometimes I do switch but don't know if its related to seizures. The most bizarre thing is though when I have a massive grand mal type pseudo seizure, I switch into a bird personality. Yes I have a bird in me. That makes no sense at all. I don't know if that is DID or schizophrenia. I lose the ability to speak all I would say is total gibberish and also believe I can fly. When I am in unknown places I sometimes switch into a 5 year old. I have autism and that is very stressful for me, even if its fun like a vacation.
