stress cause night seizure?

Hi everyone, can someone tell me if tiredness and stress can cause nocturnal seizures in people with epilepsy even though they have never had a nocturnal seizure before? I'm asking because I'm pretty sure I had a noturnal seizure recently but as far as I know, I've never had one before. I have complex partial seizures quite often and if it wasn't for my medication I'd be having grand mals too. When ever I did have grand mal seizures at night, I always knew about them because I was awake at the time before it would happen or I'd wake up from my sleep and then have a seizure. I always knew. but recently my partner woke me up from my sleep because I leaped in the bed quite violantly and he thought I might be going into a seizure. I was confused when he woke me up and I fell asleep pretty quickly soon after that too. In the morning I woke up with blood on back of my hand from some where I was bleeding during the night. My guess was from mouth because my left cheek was a bit numb. My head was sore and my neck and shoulders were very stiff and sore. Later I discovered my head on the left side was sore to touch like a bruise but i dont remember banging it anytime. my partner didn't hear anything during the night either. do you think it's possible he was so fast asleep that he heard nothing? I have been stressed out lately you see with exams coming up and my grandad being not well and I need to know if it's possible for night seizures to suddenly occur in someone when it never did before. I have had seizures now for 20 years. any thoughts are welcome! Would be very much appreciate Thanks in advance Quirky
