Are adult night terrors a one night thing, or are they reoccuring?

I am almost positive I went through my first night terror this morning, just gonna copy & paste what I wrote in another question: I remember trying to fall asleep with stupid anxiety over sleep paralysis since I did some reading on it. Fell asleep eventually (5 am), woke up two hours later thanks to my alarm. As soon as I opened my eyes I started screaming, had a HORRIBLE feeling of fear and ran out of my room. Can't remember dreaming of anything. Throughout the week, I seem to have been having heavy night sweats as well. Are these going to happen often?
