Dreams and Nightmares
Most of people spend six years or more of their lifetime dreaming. Dream is a semi-conscious state where we have absolutely no control over our thoughts and expressions. It is proven that all of us dream at least twice or more in our sleep though we may not remember when we get up. Interesting facts is that our body is paralyzed during our sleep probably to prevent the body from acting out dreams. What is important for people that have nightmares is to start dreaming lucidly so they could control the imaginary experiences in the dream environment.
