Hi Alan,

Welcome to the community. Freezing is a natural reaction from the mind to the body in states off unknown. I am not an expert by any means in that field, but I have chatted about it with professionals and read a bit also. Its like when someone is about to be hit by a car, they freeze, instead of jumping out of the way. Why? Because the mind is overloaded with immediate fear and emotion, instead of being able to cognitivally process the though of jumping clear. When you see someone jump clear, or remove themselves of a dangerous and iminent situation, it is generally because they are very mentally strong, and they process thoughts on the immediate occurence, and don't allow fear to cloud the judgement. Fear is a natural emotion, and your rightful to have fear when being within a situation you have no control.

Another example is a shark presence, in that it was only discovered that people are to freeze when a shark is around, as the mind and body did this naturally, thus bringing to light that freezing caused disinterest in sharks to continue with an attack.

What you felt is normal, and what your feeling now is normal with PTSD in check.
