" People with PTSD cannot find refuge even in sleep, their rest ravaged by nightmares and flashbacks. Their bodies become so overrun by danger signals that they can no longer trust their physical responses for cues as to how they should react. As Cindy described, they go immediately from stimulus to response without being able to think through or often even be aware of what triggered them. "
