Frequent Nocturnal Jerks and Automatisms

I have frequent nocturnal events (~20 per night, seconds long): sudden jerk with gasp, chewing & side-to-side jaw movements, sometimes both arms flexed in. I also get finger/wrist twitches lasting up to 20 s. On one night I had 5 abrupt jerks/thrashing of limbs and head in 2–3 s, followed by a cough. I usually go straight back to sleep or wake with confusion. Daytime events include a prodrome of nausea, slight fear, and déjà vu, followed by sudden jerks or blank spells where I can’t speak; once I smelled burning rubber. After every daytime event I feel unwell with headache and confusion for 20–30 min. MRI 18 mo ago was normal, and video-EEG was normal but without captured events. Could these represent focal seizures (temporal/insular) rather than parasomnia or apnea, and should I pursue inpatient video-EEG monitoring?
