Are seizures and sleepwalking/talking linked?

I have been accused of talking ans walking in my sleep since I was a small child. Some nights i would just talk, some nights i would walk, sometimes both or nothing. As I became an adult, I realized when I was sleepwalking because I would wake up in places other than my bed, like the stairwell of my apartment complex. I never saw a Dr about it, I just started using better locks on the exiting doors. I have also been told that I will kick and jolt violently in my sleep, which usually is followed by grinding my teeth and mumbling. I still payed no attention or talked to a Dr. However, a month ago I had a Grand Mal seizure for the first time, and have had two absence seizures since. My husband says that he is pretty sure I had a seizure in my sleep, and we are wondering if it is possible that the sleep patterns I have had since childhood are in someway related. I have been seeing a neurologist, and did the EEG on thursday, but i do not get the results until monday. Has anyone ever experienced or heard of these things being linked?
