Carolyn-

I frequently would have seizures at night while sleeping (complex partials) that would awaken me (usually) or else I would sense them while they were happening. Another big clue for me was nightmares which were very frequent and the panicked feeling I would get as part of my aura would happen sometimes awakening me. I too kept a journal of how I felt when I awoke. Generally I had a headache after I'd had a seizure (also very common since I had a brain tumor, but it was different somehow when I'd had a seizure during the night, mainly because I'd been clenching my jaw something fierce).
The nightmares have recently returned and I'm wondering if that means the seizures are returning at night again too. I feel for what you're going through.
A VEEG was very helpful for me in finding out what was going on.
