I never had a fever during my night terrors, I just woke up with feverish symptoms. I'm trying to remember is they were always the same, but it's difficult to make sense of.

Anyways, it sounds like the intense emotions you experienced are what created this reoccurring dreams. Each dream element offers diverging paths the dream can take. The more you take one path, the more likely you are to take it again. Strong emotion further reenforce the likely hood of you taking that path in the future. In your case, the super intense emotions of the night terror reinforced the paths you took the first time you had that dream, creating the recurring dream. If you want to break that cycle, you'd need to better control your emotions next time you have it.
