Last night, I had ths crazy realistic dream that I was riding around on a motorcycle. At one point, I hit a quick sharp turn, and felt like I nearly had just fell off. It was so realistic and frightening. 
Maybe something in your life  makes you very stress. You should try to relax before go to sleep.
Possibly, my dreams are often very confusing and or lonely. It is very sad. I think I need a lifestyle change, or am just too stressed at night. 
You konw, sometimes consulting  a psy is a good investment. Dont be afraid to do that.
