Did I have a seizure or just freak out?

Question

I was sleeping on the side of the bed I usually don't sleep on when I woke up. After some time I rolled over and tried to get back to sleep. I don't think I was really asleep but my body started shaking at my eyes were closed shut when I stopped shaking I gasped for air. What happened? Was it a seizure? I'm a very paranoid person and I don't let myself near any flashing images but I saw some in my dream.

Update:

When I started shaking I couldn't control myself. Maybe it was something supernatural instead? After my gasp for air I could breathe better. It felt like something had left my body.
