I recall waking up one morning and hearing a familiar voice but I was never able to answer it. No matter how hard I tried, I couldn't respond. I wasn't fully awake because I don't remember seeing anything. I have had 2 grand mal seizures in my life while I was asleep (never had an inability to speak before though) and I clearly know that I had them from the soreness that followed. The morning that I couldn't speak, I was not sore after. Is this experience related to my temporal lobe epilepsy?
