How to apologize to my cat?

I feel terrible about what happened. How can I apologize to my cat?

I have PTSD from childhood physical abuse. Last night, while I was sleeping, I had a dream where I was being held down. When I finally found the courage to fight back and shoved my attacker in the dream, I suddenly woke up and in my panic, I accidentally shoved my cat who was sleeping on my chest.I feel like such a jerk. I gave her treats and apologized, but is there any other way to show her that I'm sorry?
