Pretending to be a soldier winds me up in the army

Date: 3/12/2019

I had a dream where My younger sister and I got adopted and I went to visit the adoption family. We were in the basement and the father had some military friends over. There was a bullet proof vest on the floor I put it on and got a toy gun from my closet. I came out and the military friends were doing a room clear demonstration. I mentioned to the CO when they were done that I know why soldiers always kept there gun stocks high on the shoulder. He mentioned to me about joining and the next thing I knew, I was in a cave or something that had giant hammers like a forge. They were hammering some strange metal. My younger sister, Palmer from NCIS, a few other soldiers and i went into a watch/control tower on a coastal cliff. I saw a destroyer ship mentioned to everyone and said it fired. Every one calmly said get down and then there was a blast on the tower wall. But the hole was only like 3’ in diameter. Everyone got out and there were 2 landing craft on the shore. Everyone started firing but me and another female soldier ran down and did some hand to hand combat with them. We won and I woke up.
