Strange nocturnal happenings

Hi I've posted here before but forgot my password like a twit so had to re-register....but hopefully looking for people's experiences about nocturnal seizures. Have searched through some posts but not been able to find much. Quick story I had 3 tonic clonics last year along with some 'funny turns' and have been on lamotrigine with no further recognisable seizures BUT I've been waking up with some unexplained stuff: scratches, bumps on head and one time my right arm bent awkwardly at my side pointing towards my back. I've been under quite a lot of stress over past few months so the sleep patterns all over the place and even though that's never been a trigger before I'm keeping an eye on it. I know it's not tonic clonics as I'm functional in the morning, plus no fuzzy head/bitten tongue/soreness. I'm ringing my neurologist after the weekend but would really appreciate hearing from people with nocturnal seizures and what signs their aware of, thanks! Hope your all keeping well
