My 13 year old son dreamed of a woman coming to our house and robbing us. He said no one would listen to him?

and he tried kicking down the door to stop her. I found my son crying today and I asked him what was wrong. It continued about 40 minutes. I kept asking him what was wrong, was he in pain, was he depressed? He would kick the bed and cry. I got him up, I thought he was awake the whole time. I took him to the bathroom, I told him to hold on to me. Just kept crying. I hugged him and told him to take deep breath and he would calm down for a second or two. I took him to my bed, he was heavy and seemed like he was on drugs. His eye kept rolling back. Freaked me out. i finally, took him back to his bed and sat him up while he continued to cry. Meanwhile he was tryng to talk but I could not understand a word he was saying. Only WORK! all of a sudden he looks at me and say, What? I said What do you mean what? now he sounded very clear and no longer crying. He did not remember walking around with me. I asked him if he was dreaming and he started telling me about the dream. Please someone inturpett this sleep walking dream.
