How much stock do you put in your dreams?

I believe dreams are based on our wants, fears and reality. We see things in our dreams that have happened or come up in our daily lives.
We may not exactly remember them happening but somewhere they have entered our subconscious. I remember the flying dreams but haven't had one in many years. I remember creating a dreaming mechanism where I would dream about "things" chasing me and the only way I could escape would be to crash into the ground to wake up. I would need to jump out of windows, jump off roofs or hit the ground while I was flying to escape whatever it was I needed to escape from.
Most of the dreams I have now I don't remember. I went through a period of lucid dreaming a few years ago where I could control everything in my dreams. I haven't been able to do that again since that time. I will say that the flying dreams were always the best.
