Unknown trauma creating feelings in the body not related to thoughts

I don’t believe that all emotions are created by thoughts. I’ve had feelings in my body, which made me feel emotions that were absolutely not related to any thoughts I had at that moment.

I have 3 questions :

Where does trauma fits in the equation that is taught here?

What about the emotions that are not related to any thoughts?

What about the unconscious programming that creates emotions and is not related to thoughts?

Thank you for helping me understand this part better.
