That question would be best to take to your doctor especially if you're concerned about it. We can't really help you over a simple Q&A site. :)
If i have a seizure in my sleep do i have epilepsy because i feel it only happens when i stress myself out?
That's probably something you would want to talk to a neurologist about.
As the others said you should see your doctor about it. Seizures are something you need to have checked.
