Epilepsy Forum - Parasomnia Or Nocturnal Epilepsy?

I have some quite disturbing episodes in the night. I wake up with a massive jolt (usually an hour or two after going to sleep) and feel violently sick immediately. I normally try to make it to the bathroom incase I am ill but often don't make it as have to lay on the floor due to feeling so unwell and unsteady and my head so heavy. My whole body is buzzing inside (almost like a strong electrical current in my arms and legs), I feel incredibly hot inside but my outside body is cold (but sweat will be dripping down my neck), my body makes all the motions to be sick (not dry retching, just throat convulsing upwards) but I never have been sick. My breathing isn't abnormally fast. I normally just lay on the floor and try to keep as calm as possible until symptoms past. I feel very disorientated during this time and think I lose vision/have disconnected thoughts. I sometimes have lost consciousness as the buzzing gets worse (have woken up down the side of the toilet with bruised head). Then I come round a few minutes later. I'm very grey but the symptoms have totally gone (no nausea, no buzzing, I’m totally with it, like total calm after the storm) and I so I just go back to bed to sleep (if I’ve made a mess on the floor, spilt water, I just clear it all up and am totally ‘operational’) but I will feel shattered the next day. I have lost consciousness on occasions and woken up on the floor, and friends have witnessed me shaking, heard my head banging against the door or heard growling like sounds/struggling to breath sounds. Often the day leading up to the bad night I will feel hypersensitive physically and have a very bad headache. The 'episodes' are often near the end of my menstrual cycle. I had a five day/night sleep study but didn't have a full on episode in that time - the hospital diagnosed parasomnia but I do feel there is more to it than that. On a normal night without such symptoms, I will still wake up with scratches on my face and top body, and family have told me that my arms literally attack myself even though my face looks in peaceful sleep. I think I bite my tongue as sometimes wake up with blood in my mouth (but never sure this is just from my gums). Its hard to know how often I have disturbed nights as I live on my own. Any views? I'm sure it affects my daytime health more than I realise and worry it will worsen if I get pregnant/damage my baby.
