Have you ever experienced controlling your dreams?

I had this dream wherein me and my mom were walking inside a shopping mall. We decided to go to the comfort room to pee. To my delight, I saw my classmates inside the room so we chatted for a bit. Suddenly, someone screamed. I looked behind me and I saw a girl slowly coming out of a toilet bowl. She looks a lot like sadako, dressed in white and her long black hair covered her face. At that point, I don't how it happened but I became conscious that it's just a dream. That I have to get out of that place as soon as possible. So, I grabbed my mom's hand and we ran as fast as we could. I thought of saving my classmates but I know that it's just a dream and I don't want to see the face of that girl because I know that I if did, it'll be a nightmare. When we got out of that shopping mall, I woke up, breathing heavily and sweating as if I really ran for it. It's a very weird experience and I never had a dream like it after that. How about you? Have you also experienced being aware that you're in a dream that you controlled your actions during that dream of yours?
