I know this may sound crazy.. but could my epilepsy be what causes my sleep disorder?

I have had epilepsy for about 3 years, I know that is odd seeing how I am 18, I have had seizures in my sleep.. its the most uncomfortable thing I have ever expierienced, Its like your holding on to a steering wheel spinning in circles at 90 mph and I know exactly what is happening but cant wake myself up.. I litteratly try so hard to pull myself out of it but theres nothing I can do! theres been times I have waken my friends up in the night by shaking and talking in my sleep.. sometimes just one or the other, I havent had an "episode" for about a 6 months now.. meaning a seizure, but I talk in my sleep about every night.. could this have anything to do with my epilepsy? Its driving me crazy..
I have had MRI's, 72hr EEG's, catscans.. everything.. they said I have too much blood in my brain basically. They haven't determined exactly why this is happening to me.. also, my dad had seizures when he was a kid, he took medicine for it and it eventually went away.. they havent even mentioned putting me on any type of medications..
I also forgot to add my dad was recently diagnosed with sleepapnia.. could that be what it is? what exactly is sleepapnia?
