Weird feeling while driving, is this normal?

this happens to me a lot too. my therapist said this is the additional fight/flight response, and it’s the freeze. it’s dissociating, essentially, but you just feel like you can’t do anything because you’re in that “frozen” state and don’t know how to snap out of it because your limbic system (part of your brain that detects danger) thinks that there’s a threat still

This has happened to me before when I got into an accident a few years ago. Instead of panicking, my face also flushed and I got that disconnected feeling as well. All I can really attribute it to is a form of protection. Instead of going through a shock your body's reaction is to sort of disconnect itself from the situation. I notice that for me particularly this happens more if I've been under a lot of stress or have had many anxiety attacks prior, it's like the mind shuts itself down instead of going into a really bad panic that could potentially result in a hospital visit etc
