First person shooter game triggered a panic attack. Normal?

My son bought me a video game player for Father’s Day. Over the weekend we tried to play a co op game of Call of Duty that included a scenario placed in an area I was deployed to. Later that evening I had nightmares and the familiar symptoms of PTSD I figured I had left behind. I am still in a hyper vigilant state several days later. Have any of you guys experienced this? I am actively applying the measures the VA taught me and do not want to visit with them any more. (You vets will understand that)
