Undiagnosed neuro condition

Idk if anyone on this app will know but I figured it wouldn't hurt. Has anyone heard of a neuro condition where the person has a blackout where they do weird movements such as dancing, rolling, growling, yelling, etc and then has complete amnesia of the entire event. May be or may not be connected to seizures (they started around the same time.) All neuro tests come back normal. Any ideas or experiences with something similiar?
