I just happened across this article that explains what takes place in the brain when someone experiences a flashback. I am so grateful I found it and can post it.

There is another link you can click on that describes how trauma can also create a savant to kick in which I think is also amazing. I am going to post this article in the complex PTSD forum as well.
