Fully Awake During Fever Dream

Whenever I have a high fever, I will occasionally wake up with a cold sweat in the middle of the night. When I wake up, I am scared out of my mind. I keep repeating "why me" and "it's all my fault". After the terror is over, I remember every last detail. During the terrors, I feel as if the world is ending and it's all my fault. Something I did has caused the end for everyone. I feel completely helpless as my parents try to calm me down. I get up and pace around holding my head, trying to cope with the fact that the end of the world is my fault. I eventually give in to the fact that there's nothing I can do about it so I attempted to just close my eyes and fall back asleep. It's as if the fever has implanted something in my mind. This is not something that is easy to explain for me. These terrors also happen maybe twice a year, so it is nothing lige-altering. Any enlightenment on this topic would be greatly appreciated.
