I've had this happen a few times. Sometimes I am aware that I am dreaming. Sometimes during a nightmare I will say to myself "Wait a minute, don't freak out this a just a dream." So I don't get scared. There was one dream where I was being chased or something then I stopped and realized that I was dreaming. I told myself that I would count to 3 and on 3 I will wake up and I did wake up on 3. You know when it's really fun to control your dreams is when you're having a dream about sex. I've had this happen a few times. I'll be dreaming of having sex with my hubby and I find I can control everything we do in the dream. Now that's really awesome!
