Need help knowing if my anxiety is changing and what I just experienced?

I was sleeping, woke up and decided I was going back to bed and started dreaming I believe.

However in my dream. I was in college, me and the guy beside me were handed notes from the teacher. The guy beside me started becoming really obnoxious and loud. I kept responses to a minimum.

Suddenly, his hand is on my waist, around it even. And his other hand grabs one of my hands ane he starts getting louder. And I’m a guy so this was already weird.

I told him to go away and he bit my neck, relatively hard. My eyes were open as I thought about this but I didn’t see anything so I don’t think it was sleep paralysis, at least I’m not sure.

Suddenly it felt like a claw was sinking into my hand and waist, and my fight or flight response kicked. I was against my bed but filled with abit of adrenaline. It wasn’t a full on rush, and I’m a relatively calm dude so I was thinking calmly and I acted violently.

My hand that was being held onto snapped the dream dude’s wrist, and then I grabbed him by the upper and lower mouth. As soon as I broke it, I sat up and felt completely awake.

First thing I did was check for a bite mark on my neck or blood leaking. It felt somewhat real and I’ve never had anything like this happen before? I felt this stuff on my real body, it felt like my muscles on my neck and waist were just being having sharp teeth and claws penetrating them. My body was moving in real life near the end of that dream, specifically during the end of it. And I vividly recall breaking the dream guy’s hand off of his wrist and feeling his bone against my arm as he continued to poke me with it. Any ideas?
