Nocturnal panic attacks or sleep apnea?

First off, I have mild derealization which I've had for the last 6 months that is constant but yet getting better here and there. Anyways, about 1-2 times a week I'll wake up in the middle of the night with real bad depersonalization, derealization, and dizziness. After it happens it usually makes me panic or puts me in a real high anxiety state but I just walk around or find a way to distract myself and it all goes away after like 5-15 minutes returning me to my normal level of derealization. Could this be a form of sleep apnea or perhaps a nocturnal panic attack?

Thanks
